Limerence

A psychologically informed reality check on crushes, dopamine, and why you’ve refreshed their Instagram feed 47 times today

You don’t feel like eating when you’re normally hungry. You can’t focus. Your mood depends entirely on whether they used a heart emoji or a thumbs up. You are not “in love.” You are in limerence.

As both a researcher and therapist, let me say this gently: limerence is not a soulmate signal. It’s a neurochemical event. Let’s unpack it.

What Is the Psychological Definition of Limerence?

The term limerence was coined by psychologist Dorothy Tennov in her 1979 book Love and Limerence. She used it to describe the intense, involuntary state of romantic infatuation characterized by intrusive thinking, longing, and emotional dependency on another person.

Limerence typically shows up at the early stage of attraction, when:

• Passion is high

• Curiosity is heightened

• Uncertainty fuels fixation

During limerence, we see:

• Increased dopamine (reward and motivation)

• Increased norepinephrine (arousal, alertness, excitement)

• Increased oxytocin (bonding and attachment)

• Decreased serotonin, which has been observed in early romantic love and mirrors patterns seen in obsessive-compulsive presentations (Marazziti et al., 1999; Fisher et al., 2005)

In plain English: your brain is lighting up like you just won a prize, drank three espressos, and got to play with a puppy all at once.

How Do You Know If You’re in Limerence?

You might be in limerence if:

• You think about them constantly (and I mean constantly).

• Your thoughts feel intrusive or hard to redirect.

• Your mood depends on their responsiveness.

• You analyze texts like you’re decoding a CIA document.

• You feel euphoric when they engage and devastated when they don’t.

Tennov emphasized mood dependence as central to limerence. Your emotional state rises and falls based on tiny signals.

They text back? Elation.

They take four hours? Existential spiral.

That volatility is not love. It’s uncertainty mixed with dopamine.

The “Stages” of Limerence (Even Though It’s Not Technically a Stage Theory)

Tennov didn’t frame limerence as a neat three-step process. But many people experience something like this:

1. Initiation

This is the spark. You notice them more. You replay conversations. You feel anticipation.

The brain’s reward circuitry starts to engage.

2. Crystallization

Now the fantasy solidifies. You idealize them. Red flags become “quirks.” Ambiguity becomes “mystery.” Your brain fills in gaps with flattering projections. You see the world through rose-colored glasses. Your mood becomes deeply entangled with theirs.

3. Deterioration (or Transition)

Eventually, one of two things happens:

• The feelings are reciprocated and a real relationship forms.

• The uncertainty resolves (often painfully), and limerence fades.

If unrequited, deterioration can feel like withdrawal. And biologically, that’s not an exaggeration. This explains why “just move on” is terrible advice.

How Long Does Limerence Last?

Relationship scientists often note that the intense infatuation phase of romantic love lasts about 18 months, plus or minus six.

Limerence can last weeks. It can last years. Especially when:

• The relationship is ambiguous.

• There’s intermittent reinforcement (inconsistent availability).

• The fantasy is never fully tested by reality.

Situationships fuel limerence as uncertainty keeps dopamine activated.

Can Limerence Turn into Love?

Yes, but not automatically. Limerence is built on projection and possibility. If, underneath the initial focus, two people build a stable friendship and emotional foundation, limerence can evolve into attachment-based love. If not, limerence burns hot and collapses.

How to Get Over Limerence (Without Pretending You’re Fine)

First: do not shame yourself. Limerence is involuntary. It’s not weakness; It’s wiring.

Second: don’t force suppression. Trying to “just stop thinking about them” often backfires. Suppression increases intrusive thoughts (classic rebound effect).

Instead:

• Name it- Calling it limerence creates psychological distance.

• Reality-test gently- Notice where you’ve filled in blanks with fantasy.

• Widen your life-Not to distract, but to re-balance your reward system.

• Process the loss-If it’s unrequited, you’ll likely feel grief.

Getting support from friends can help regulate your nervous system and therapy can help unpack attachment patterns and cognitive loops. Over time, the neurochemical surge subsides and your brain recalibrates.

The Hard Truth

Limerence feels magical because it takes over your reward circuitry. Love is quieter. It is less volatile. It is more stable. It does not require decoding emoji punctuation for emotional survival. If your “connection” feels like a dopamine slot machine, step back. Real intimacy does not depend on intermittent reinforcement.
