Love or Limerence?

When Intensity Feels Like Intimacy - Especially With an ADHD Brain

There is a question we rarely ask while falling for someone:

Do I actually love this person - or have I become attached to how this person makes my brain and body feel?

Because the two can feel remarkably similar.

You think about them when you wake up.

A message changes your mood.

You replay conversations.

You notice tiny shifts in tone.

You miss them intensely.

Attraction feels enormous. Waiting feels enormous. Reconnection feels enormous.

Surely that means you're falling in love?

Maybe.

Maybe something else is amplifying the experience.

And maybe both are true.

The useful question isn't:

“Are my feelings too intense?”

It is:

“What is this intensity made of?”

Intensity is not intimacy

Intensity tells you how activated you are. Intimacy tells you how deeply two people actually know, trust and reveal themselves to one another.

And this is where time and experience matter.

Some people can experience extraordinary chemistry, attraction, connection or limerence towards somebody they barely know.

Some people describe themselves as falling in love very quickly.

For others, romantic love develops much more gradually.

There is no universal romantic timetable.

You may discover within hours that you share humour, intellectual chemistry, sexual attraction, values, interests and similar ambitions.

That experience can be completely genuine.

But there is a difference between experiencing compatibility and having enough information to know how compatible you actually are.

I cannot know after three extraordinary dates how you handle sustained stress, disappointment, conflict, boredom, money, responsibility, boundaries or repair.

Early intensity isn't necessarily false.

It simply contains more unknowns.

What actually is limerence?

Psychologist Dorothy Tennov coined the term limerence in her 1979 book Love and Limerence to describe an intense state of romantic preoccupation involving powerful longing for reciprocation.

For something discussed so frequently online, the scientific research base is surprisingly young.

In 2025, Marshall and colleagues developed the Limerence Questionnaire-11 (LQ-11) across two samples of 269 and 401 participants who had experienced limerence.

Two dimensions emerged:

1. Intense Need for Attachment

A powerful need for closeness and reciprocation from the person.

2. Neglect to Self and Others

Preoccupation becomes sufficiently consuming that responsibilities, relationships, sleep, appetite or aspects of one's own life may begin to suffer.

The researchers themselves describe this as preliminary evidence and emphasise that further research is needed into the antecedents and consequences of limerence.

They describe limerence as an overwhelming and debilitating experience involving the intense and often obsessive attachment towards a person who becomes the limerent object, which when left unharnessed, typically results in negative outcomes.

Then came a much larger 2026 investigation into impairing limerence.

Evans and colleagues describe it as a chronic, involuntary and intrusive form of romantic obsession. In their experience-sampling study, limerent thoughts occupied approximately half of waking thought, and negative emotional states-particularly sadness and loneliness-were associated with limerent cognition.

So limerence isn't simply:

"I really, really like somebody."

Nor is it simply:

“I think about them all the time.”

And this is where the distinctions become important.

Love, limerence, hyperfocus, emotional dysregulation or rejection sensitivity?

Imagine you haven't heard from somebody you're falling for.

You spend the afternoon thinking about them.

What does that mean?

Potentially very different things.

Romantic love says:

“I want you.”

There is attraction, affection, longing, care, desire for closeness and increasing interest in the actual person.

And romantic love itself can involve extraordinary preoccupation.

A 2024 study of people who were in love found that participants estimated thinking about their beloved approximately 67% of the time generally and up to 42% during an attention task.

Even more interestingly, they overwhelmingly enjoyed those thoughts.

Greater beloved-focused thinking was associated with infatuation or passionate love, but not companionate attachment.

So:

Thinking about somebody constantly does not, by itself, tell us that somebody is limerent.

Hyperfocus says:

“My attention keeps locking onto this.”

Hyperfocus is primarily about attention: unusually intense absorption accompanied by reduced awareness of competing information and sometimes difficulty shifting attention elsewhere.

People frequently use the expression “ADHD relationship hyperfocus.”

But we should be careful.

Hyperfocus research itself remains developing, and research has not established “romantic hyperfocus” as a distinct ADHD trait.

Person-focused attentional capture may help describe someone's experience.

Emotional dysregulation says:

“This feeling is difficult to manage.”

ADHD is often linked with emotional dysregulation.

That matters because romance is already emotionally salient.

For some people with ADHD:

Attraction can feel bigger.

Preoccupation can feel bigger.

Waiting can feel bigger.

Rejection can feel bigger.

Ambiguity can feel bigger.

Reconnection can feel bigger.

This tells us something about the volume and regulation of emotion.

It doesn't tell us what the emotion means.

Rejection sensitivity says:

“The possibility of rejection feels exceptionally threatening.”

The term Rejection Sensitive Dysphoria (RSD) is very common with ADHD.

Emerging qualitative research has described extreme emotional distress around perceived rejection and criticism among people with ADHD

A delayed message can become:

They haven't replied.

Then:

Something has changed.

Then:

They're rejecting me.

Then:

I'm going to lose them.

The external event hasn't changed.

Its emotional meaning has escalated.

Limerence says:

“I need to know whether you choose me.”

Here, attention becomes disproportionately organised around the person and reciprocation.

Do they want me?

Why haven't they replied?

What did that message mean?

Are they pulling away?

Are they thinking about me?

Will they choose me?

And particularly when limerence becomes impairing, attachment and preoccupation begin displacing other parts of life.

The difference in one glance

Romantic love:

I deeply desire, care for and feel drawn towards this particular person.

Hyperfocus:

My attention has become unusually absorbed.

Emotional dysregulation:

My emotional response is unusually difficult to regulate.

Rejection sensitivity:

Possible rejection or criticism carries unusually powerful emotional meaning.

Limerence:

My attachment, preoccupation and need for reciprocation are becoming consuming-and may increasingly interfere with the rest of my life.

These are not mutually exclusive experiences.

Someone can experience limerence without ADHD.

Someone can experience hyperfocus, RSD or emotional dysregulation without limerence.

And somebody with ADHD can simply be passionately in love.

So what is romantic love?

Researchers including anthropologist Helen Fisher have conceptualised intense romantic love as a motivational system focused on a particular individual, involving powerful attention, desire, longing and reward-related processes.

But thousands of years before neuroscience started putting lovers inside brain scanners, Greek thought had already recognised something that English often obscures:

love is not one experience.

ἔρως - erôs evokes passionate, desiring love: something close to what we mean when we say we are in love.

φιλία - philia encompasses affection and valued relational bonds.

ἀγάπη - agapē, particularly in later Greek and Christian traditions, developed associations with giving and devoted forms of love.

There is another ancient perspective worth bringing into the conversation.

In 1 Corinthians 13, Saint Paul writes about agapē (ἀγάπη)-not as the intensity of desire or the experience of being in love, but through the qualities love expresses: patience, kindness, humility, endurance and an orientation towards truth.

This is not a scientific definition of romantic love, and Paul was not writing a modern psychology of relationships. But the contrast gives us another useful lens.

Erôs draws our attention to desire. Limerence draws our attention to preoccupation and reciprocation. Agapē asks us to consider how love behaves.

Romantic love can contain:

attraction + longing + sexual desire + tenderness + admiration + care + focused attention + emotional connection + desire for closeness.

And romantic love is not the same thing as compatibility.

You can be extraordinarily compatible with somebody and never fall in love with them.

You can love somebody profoundly and discover that you cannot build a functional life together.

You can have chemistry without compatibility.

Attachment without relational health.

Compatibility without desire.

And you can experience something extraordinary:

chemistry + connection + attraction + admiration + respect + intimacy + compatibility + reciprocal attention + romantic love.

The purpose of discernment isn't to explain that experience away.

It is to understand what is actually there.

Thinking about them constantly doesn't settle the question

Compare two people saying:

“I think about them constantly.”

One means:

“I'm ridiculously in love. They keep appearing in my thoughts, it feels wonderful, and I'm still living my life.”

The other means:

“I can't stop analysing whether they want me. My mood depends on their signals. I'm struggling to concentrate. I'm neglecting myself and I need to resolve the uncertainty.”

Both contain preoccupation.

Their psychological architecture is different.

So don't ask only:

“How much am I thinking about them?”

Ask:

“What kind of thinking is this - and what is it doing to me?"

Sometimes the person isn't only touching your heart. They're touching an old wound.

This is where the emerging research becomes particularly interesting.

The 2026 study of impairing limerence found elevated adverse childhood experiences and insecure attachment among participants experiencing it.

Separately, a major 2026 meta-analysis examined 211 studies, 228 independent samples, 1,304 effect sizes and 82,376 participants.

Childhood maltreatment was associated with both adult attachment anxiety and attachment avoidance.

This does not establish:

childhood wound → limerence.

It doesn't mean everybody who experiences limerence had a traumatic childhood.

And it doesn't prove that people unconsciously select partners who recreate their childhood wounds.

But it gives us a reason to become curious about what particular types of relationships might be activating.

Sometimes:

“Will you choose me?”

may contain:

“Am I finally going to feel chosen?”

Sometimes:

“Why haven't you replied?”

contains:

“Have I done something wrong?”

Sometimes:

“Why can't you give me what I need?”

touches something older:

“When did I learn that my needs were too much?”

Or:

“What part of me still believes love has to be earned?”

A romantic trigger may be happening today because of an old wound.

That doesn't make present love not real.

Present love and past trauma can coexist.

Relationships can become mirrors

This is where I use the concept of the shadow partner.

I use shadow as an archetypal and therapeutic lens influenced by Jungian psychology.

Carl Jung used the concept of the shadow for aspects of ourselves that sit outside the identity we consciously recognise.

Relationships can sometimes illuminate exactly those parts.

The needy part.

The angry part.

The jealous part.

The vulnerable part.

The part terrified of abandonment.

The part afraid of being truly seen.

The part that learned:

Don't ask for too much.

Don't be difficult.

Be impressive.

Be useful.

Be desirable.

Don't need anybody.

Earn love.

Sometimes we encounter somebody whose relational pattern activates exactly that hidden narrative.

I call this a shadow partner.

Not because destiny sent them to heal you.

Not because dysfunctional relationships are somehow more spiritually meaningful.

And not because research proves that we universally “attract our wounds.”

The research supports a more grounded observation: adverse childhood relational experiences are associated, on average, with later insecure attachment.

So use the shadow as a mirror.

Instead of:

“Was I destined to meet this person?”

ask:

“What is this relationship showing me about myself?”

When the shadow meets limerence

Now imagine several processes arriving simultaneously.

There is extraordinary chemistry.

You genuinely care about the person.

They activate an old fear of not being chosen.

Contact is inconsistent.

Your attention becomes captured.

Rejection feels unusually intense.

Uncertainty keeps the relationship mentally salient.

Your imagination begins filling informational gaps.

Now you aren't responding simply to:

the person.

You may be responding to:

the person + romantic love + chemistry + attachment activation + attentional capture + emotional amplification + uncertainty + memory + fantasy + hope.

No wonder it feels enormous.

Suddenly, you have constructed an entire psychological research department around one human being.

But analysis can create an illusion of intimacy.

Thinking about somebody for 100 hours isn't the same as spending 100 hours discovering who they actually are.

One generates interpretation.

The other generates information.

Potential is limerence's perfect foundation.

We know fragments.

Imagination completes the picture.

The question gradually stops being:

“Who is this person?”

and becomes:

“Who could this person become if everything goes the way I hope?”

Maybe they'll commit.

Maybe they'll communicate differently.

Maybe they'll become available.

Maybe once they trust me...

Maybe once life becomes less stressful...

Potential allows us to become attached not only to the person who exists, but to the person we imagine they might become.

This creates what I call the fantasy gap:

the distance between the relationship you actually have and the relationship you believe could exist.

Romantic love can contain idealisation too, particularly early on.

The important question is what happens when reality supplies new information.

Love eventually has to meet the ordinary

Possibility can remain perfect.

Human beings cannot.

Eventually there are:

Schedules.

Values.

Conflict.

Reliability.

Money.

Sex.

Communication.

Boundaries.

Boredom.

Responsibility.

Disappointment.

How does this person behave when they don't get what they want?

How do they repair after hurting you?

Do their actions match their words?

Can they make room for your needs?

Can you make room for theirs?

This information doesn't determine whether you love somebody.

Sometimes reality tells us:

“I love you deeply - and this relationship still doesn't work for me.”

Love and relational viability are different questions.

One of the biggest traps: confusing inconsistency with chemistry

Someone is intensely affectionate.

Then distant.

Then intensely affectionate again.

Reconnection feels extraordinary partly because disconnection felt uncomfortable.

That doesn't automatically mean they're manipulating you.

They may be inconsistent, ambivalent, avoidant, distracted, overwhelmed-or simply want something different.

But your nervous system doesn't require deliberate manipulation to become caught in the contrast.

So don't ask only:

“How strongly do I feel about them?”

Ask:

“What happens to me in this relationship?”

Do I become more grounded or more preoccupied?

Does my world expand or contract?

Can I sleep?

Work?

Exercise?

See friends?

Pursue my goals?

Can I tolerate space?

Can I see behaviour I dislike without immediately explaining it away?

Can I simultaneously hold:

“I want you enormously”

and

“I'm still observing whether this relationship works for me”?

That is discernment.

Love can tolerate information

Not because love always survives information.

Sometimes information deepens love.

Sometimes information tells you the relationship needs to end.

But reality is allowed into the room.

When attraction becomes consuming, something different can happen.

A boundary gets crossed.

They didn't mean it.

Needs aren't met.

I need to give it more time.

Values conflict.

Maybe they'll change.

Something doesn't add up.

Maybe I'm overthinking.

Notice what happened.

We stopped discovering who the person is.

We started negotiating against ourselves to preserve access to them.

That is self-abandonment.

And chemistry doesn't transform self-abandonment into intimacy.

Limerence asks: “Do you choose me?”

Limerent dynamics can generate endless interpretation.

Do they like me?

Why haven't they texted?

Are they falling for me?

Are they jealous?

Are they afraid of losing me?

What did that message mean?

Romantic love cares about reciprocity too.

Of course we care whether somebody we love loves us back.

But as we actually know another person, the questions become larger:

Do I really know you?

Do I respect you?

Do I admire you?

Can I trust you?

Can we repair?

Can we communicate?

Do our words and behaviour align?

Are we sufficiently compatible for the relationship we both want?

Can I become more vulnerable without becoming less discerning?

And:

“If you never changed from who you are today, would I still choose this relationship?”

Limerence can survive on possibility.

Love increasingly encounters the whole person.

The person who activates the wound isn't necessarily the person who has to heal it

This may be the most liberating part.

If somebody activates the part of you that feels unwanted, your only options aren't:

make them choose me

or

stop feeling anything.

There is another possibility:

Meet the part of yourself that has been activated.

Let the feeling exist before immediately acting on it.

Listen to what it needs.

Ask:

What am I afraid this situation says about me?

When have I felt this before?

What part of me believes being chosen by this person would finally prove something about my worth?

When did I learn that my needs were too much?

Then bring care there.

And follow insight with behaviour.

Practice one act of self-respect.

Speak honestly.

Ask the question.

Say no.

Keep the boundary.

Stop checking.

Return to your work.

Call your friend.

Eat.

Sleep.

Move.

Create.

Come back to your own life.

Come back to yourself.

Not as a strategy to make somebody chase you.

As an act of wholeness.

The 24-hour reality test

When you're highly activated by a romantic interaction, don't necessarily decide what it means immediately.

Let the emotional intensity settle.

Then separate three things:

FACT

What objectively happened?

STORY

What meaning is my mind attaching to it?

STANDARD

Regardless of their intention:

Does this work for me?

That final question returns agency.

Because relationships become very different when we stop becoming detectives of another person's psychology and start becoming observers of reality and guardians of our own standards.

Regulation doesn't mean becoming less passionate

I don't want people with ADHD becoming suspicious of intensity.

The research on romantic love itself shows that intense beloved-focused thinking can be part of being passionately in love.

The objective isn't emotional neutrality.

It is enough internal regulation that:

Desire does not remove discernment.

You can adore somebody and observe them accurately.

You can miss somebody without abandoning your standards.

You can experience rejection without automatically converting it into a verdict on your worth.

You can tolerate uncertainty without making its resolution your full-time occupation.

You can want somebody enormously without turning their potential into evidence.

You can allow another person to reveal themselves rather than endlessly interpreting them.

Perhaps the real counterweight to limerence isn't simply romantic love.

Perhaps it is self-leadership.

Odysseus did not defeat the Sirens by pretending their song wasn't compelling. He created a structure for the moment when it would be. Self-leadership doesn't require the absence of desire.

Self Leadership:

The ability to remain connected to yourself while becoming deeply connected to somebody else.

To meet the part you once learned to hide.

To question the belief that love must be earned.

To become increasingly authentic beneath everything you learned to become in order to be chosen.

Become your own soulmate first.

Not because you shouldn't need people.

We are relational beings.

Not because you need to be completely healed before somebody can love you.

You don't.

But because romantic love should not require your disappearance.

So perhaps the most useful question isn't simply:

“Is this love or limerence?”

It might be:

“Can I love this person without leaving myself?”

That is where the conversation gets interesting.
