Limerence & obsessive crushes

What is limerence?

When a crush becomes all-consuming.

Limerence is an involuntary, intense fixation on another person. Psychologist Dorothy Tennov described it in the late 1970s, in her 1979 book “Love and Limerence”. The person someone is fixated on is sometimes called the “limerent object”.

It is often described as an overwhelming longing for another person’s attention and approval, usually without those feelings being returned. Not knowing whether the other person feels the same is part of what keeps it going.

Limerence is not an official diagnosis, and nobody yet knows how common it is. Research is still small: one review of the literature found about 156 peer-reviewed papers since 1979 that mention the word, and only a few dozen that actually study it.

Feelings aren’t failures. Limerence can happen to kind, sensible people of any age, single or partnered. It can be very painful, and it does end.

Love or limerence?

How a fixation differs from love that goes both ways. Tap any card.

Love grows from knowing someone, flaws and all, in a relationship that goes both ways. Limerence is often one-sided and built on fantasy and longing. It can feel thrilling, but it also feels out of control.

🌀 Signs of limerenceIt takes over your thoughts whether you want it to or not.

Common signs

  • Checking their texts or social media again and again
  • Fear of rejection, and loneliness when they are unavailable
  • Intrusive thoughts and long daydreams
  • Putting most of your time and energy into thinking about them
  • Putting your own needs aside
  • Seeing them as perfect and overlooking red flags
  • Swinging between euphoria and despair based on their attention
💓 Signs in your bodyLimerence is felt physically, not just in your head.
Read more

People describe a racing or pounding heart, sweating, nausea, loss of appetite and poor sleep. These are signs of a body on high alert.

Some people notice withdrawal-like feelings when they are apart from the person, such as aches in the chest or stomach, trouble sleeping, irritability and low mood.

Slow breathing, a walk or a regular sleep routine will not end limerence, but they can calm the body enough to think more clearly.
😇 The “halo” effectThe person can seem flawless, more fantasy than real.
Read more

In limerence, the other person often seems perfect, and any flaws or warning signs get explained away. This is sometimes called the halo effect.

Many people in limerence say they would not actually want the fantasy to come true in real life. The longing is for the idea of the person, not the person as they are.

🌳 What healthy love feels likeLess of a rollercoaster, and more honest and comfortable.
Read more

A real, healthy relationship may feel less dizzying than limerence, but it is more honest and comfortable. Both people know each other, flaws included, and both choose to show up.

It tends to look like

  • Feeling calmer, not more anxious, over time
  • Interest and effort going both ways
  • Keeping your own friends, interests and needs
  • Seeing the person clearly and liking them anyway

Why it happens

Brain reward systems, uncertainty, attachment and life changes. Tap any card.

There is no single cause. Brain reward systems, attachment patterns, self-worth and what is happening in your life can all play a part.

🧠 The brain’s reward systemLonging lights up the same systems as craving.
Read more

Limerence shares features with addiction: the brain’s reward chemical dopamine reinforces the pull toward the person, especially when their attention is unpredictable.

In a brain-scan study of 15 people who had recently been rejected but were still intensely in love, looking at a photo of the person activated areas linked to reward, craving and emotion control. The longer it had been since the breakup, the weaker some of this activity was.

This helps explain why “just stop thinking about them” rarely works. Your brain is not weak; it is doing what reward systems do.
❓ Uncertainty keeps it goingMixed signals feed the fixation.
Read more

Not knowing whether the person feels the same is a key part of what starts and sustains limerence. A smile one day and silence the next can keep hope, and obsession, alive.

Limerence often fades when reality becomes clear: either the feelings are returned and a real relationship begins, or it becomes clear that they are not.

🪢 Attachment & self-worthOld fears about being loved can make it more likely.
Read more

Limerence may be linked to anxious or avoidant attachment patterns. Low self-esteem, past trauma or insecure early relationships may make someone more likely to experience it.

Things that may make it more likely

  • Anxious attachment or low self-esteem
  • Heavy social media use
  • Hyperfocus, for example in people with ADHD
  • Past trauma or insecure early relationships
The “Attachment, love & intimacy” guide explains attachment styles and how to grow more secure.
🌫️ Life changes & lonelinessIt often shows up when something feels missing.
Read more

Clinicians notice that limerence often arrives during life transitions, times of loneliness, or a sense of emptiness. The person can seem to fill a gap: excitement, meaning, being seen.

Dating apps and social media can make people feel deeply connected to someone they barely know.

Stages of limerence

It usually rises, peaks and fades. It does end.

Three common stages

  1. Infatuation: an idealised connection and lots of fantasising.
  2. Crystallisation: obsession peaks; routines change and your own needs slip.
  3. Deterioration: unmet needs and reality set in, often bringing sadness, anger or resentment.

Limerence can last from a few weeks to several years, and it can happen more than once in a life. One estimate puts a typical episode at about one and a half to three years. It eventually ends, sometimes when feelings are returned and grow into a real relationship.

⛰️ During the peakBe gentle with yourself when it is at its strongest.
Read more

At the peak, routines can change and other people may notice that you seem distracted or not yourself. This is the hardest time to make big decisions.

Try

  • Keep basic routines: meals, sleep, movement
  • Lean on one or two trusted people
  • Put off big choices, like quitting a job or ending a relationship, until you feel steadier
🍂 As it fadesSadness, anger or relief are all normal.
Read more

As limerence fades, people often feel grief for the fantasy, anger, resentment, or embarrassment about how much time it took. Some feel relief and a return of energy for the rest of life.

The “Breakups & heartbreak” guide has ideas for grieving a relationship, even one that only existed in hope.

How it can affect your life

Work, sleep, focus, mood and other relationships. Tap any card.

Limerence can harm both mental and physical health. Because it often centres on a one-sided bond with an idealised person, people can let their own lives and needs slip.

💼 Focus, work & studyDaydreams that once soothed can start to crowd everything out.
Read more

People often say the fantasy felt comforting at first, but later got in the way of work, conversations and concentration. Some people seeking help were struggling to work or focus on anything else.

Small helps

  • Use a timer: 25 minutes of focus, then a short break
  • Keep your phone in another room while you work
  • Write the thought down and come back to it later
🎢 Mood & anxietyHighs and lows can depend on one person’s attention.
Read more

Mood can swing between euphoria and despair depending on small signals from the person. Anxiety when together or apart, and loneliness when they are unavailable, are common.

In one study of people’s lived experience, many who described limerence also experienced anxiety, depression or substance use.

If your mood stays low, you feel hopeless, or you use alcohol or drugs to cope, please talk to your clinical provider or a therapist.
🔁 Thoughts that feel stuckReplaying, rereading and checking can become rituals.
Read more

Limerence can include intrusive thoughts and repeated rituals, like looking at photos or replaying past conversations. Because of this, researchers have compared it with obsessive-compulsive patterns and with addiction, while still seeing it as its own experience.

If obsessive doubts are about a partner you are already with (“Do I really love them?”), the “Relationship OCD” guide may fit better.
💍 If you’re already partneredLimerence can happen inside a committed relationship.
Read more

People who are married or in long-term relationships also experience limerence. It can bring guilt, confusion and fear of hurting people you love.

Gentle steps

  • Remember that a feeling is not an action. You can choose what you do next.
  • Limit contact with the person where you can.
  • Look at what might be missing or strained in your life right now.
  • Talk it through privately with a therapist before making big decisions.
The “Marriage & long-term partnership” and “Cheating & infidelity” guides may help.

Checking, scrolling & daydreams

Loosening the habits that keep the fixation fed. Tap any card.

Checking someone’s messages or profiles over and over is one of the most common signs of limerence. Each check can bring a tiny hit of hope, which keeps the cycle going.

🔕 Mute, don’t searchStart with the easiest step.
Read more

Experts suggest limiting social media, starting with searching for the person and checking their profiles.

Ideas

  • Archive old chats so they are not on your home screen
  • Mute or unfollow their accounts and stories
  • Move social apps off your home screen
  • Turn off notifications from them
Use the “My checking & contact plan” worksheet.
⏳ Delay the urgeUrges rise and fall like waves.
Read more

In one published case, a person reduced the time spent on limerence rituals by gradually resisting the urge to check, rethinking unhelpful thoughts, and filling time with meaningful activities. One person’s story cannot prove what works for everyone, but it shows change is possible.

When the urge to check hits

  1. Notice it: “I’m having the urge to check.”
  2. Wait 10 minutes. Set a timer.
  3. Do something with your hands or body: a walk, a dish, a stretch.
  4. If you still check, notice how you feel afterwards, without judging yourself.
☁️ Watching your thoughtsYou can notice a daydream without following it.
Read more

Some therapists use acceptance and commitment therapy (ACT) ideas: learning to notice limerent thoughts without reacting to them, making room for uncomfortable feelings, and coming back to your own values and goals.

Try

  • Name it: “There’s the story again.”
  • Imagine the thought as a cloud passing by
  • Bring your attention back to what is in front of you

Moving on

Gentle, practical steps to loosen the grip.

What can help

  • Accept your feelings without judging yourself. Feelings aren’t failures.
  • Be honest about what you need in a healthy relationship, and whether this person meets it.
  • Limit contact and mute or unfollow on social media, starting with the easiest steps.
  • Pour energy back into friends, family, hobbies and goals.
  • Practise self-compassion and build a steady sense of who you are.
🌍 Widen your worldMore people and more meaning leave less room for the fixation.
Read more

Broadening your social circle, with friends, coworkers and family, helps one person stop being the centre of everything.

Ideas

  • Join a class, team, choir or volunteer group
  • Plan one thing to look forward to each week
  • Reconnect with a friend you have drifted from
🧭 Your values, not their attentionAsk what matters to you, apart from them.
Read more

Clarifying your own values and goals, and exploring the needs the person seems to meet, can help you meet those needs in other ways.

🫶 Be kind to yourselfShame keeps people stuck. Kindness helps them move.
Read more

Experts recommend accepting feelings without judgement and relying on yourself for support, which is part of building a more secure relationship with yourself.

The “Self-compassion & your inner critic” guide has practical exercises.
Progress is rarely a straight line. A bad day after a good week is normal, not a failure.

When it crosses a line

Everyone deserves to feel safe, including the person you’re fixated on.

Many people in limerence keep their feelings private, or even avoid the person. But a fixation should never turn into following, monitoring or pressuring someone.

Signs it is time to stop and get help

  • Contacting someone who has asked you to stop
  • Following them, turning up where they will be, or watching their home
  • Making fake accounts to see their posts
  • Tracking their location or reading their private messages
If a crush ever turns into following, monitoring or contacting someone who has asked you to stop, please reach out for help right away. A therapist can help you stop safely and without judgement.
If someone else’s fixation is making you feel unsafe, the “Stalking & feeling unsafe” guide explains your options. If you are in danger, call 911.

Supporting someone

It can be frustrating to watch a friend pour their heart into someone who doesn’t return it. Patience and kindness help more than logic.

💬 What to sayListen first.
Read more

Try

  • “That sounds exhausting. How are you holding up?”
  • “You don’t have to have it figured out.”
  • “Want to do something to take your mind off it?”
  • “I’m here, even if you need to talk about them again.”
🙊 What not to sayMocking or lecturing adds shame.
Read more

Try to avoid

  • “Just get over it.”
  • “That’s pathetic.”
  • “They’re obviously not interested.”
  • Sharing their feelings with others, or with the person

Shame makes people hide. Feeling accepted makes it easier to step back.

🧺 Practical helpBe part of their wider world.
Read more

Ideas

  • Invite them to plans that have nothing to do with the person
  • Offer to be their “check-in” when they want to text the person
  • Help them notice small wins: a day without checking, a good night’s sleep
🔋 Caring for yourselfYou can care and still have limits.
Read more

It is okay to say you need a break from the topic sometimes. If you are worried about their safety or someone else’s, encourage them to talk to a professional.

When and where to get help

Signs it’s time to reach out, and who can help.

It may help to talk to someone if…

  • It keeps coming back, with one person after another
  • It is affecting your sleep, eating, work or relationships
  • You feel powerless to stop checking or contacting them
  • You feel hopeless, very low, or are using alcohol or drugs to cope

If limerence leaves you feeling powerless or keeps coming back, a therapist can help you understand where it comes from and break the cycle. Cognitive behavioral therapy (CBT) is one option. Your clinical provider, a counsellor or a trusted faith leader can also help you find support.

If you’re in crisis, call or text 988 (U.S.), or text HOME to 741741. If a life is in danger, call 911. Outside the U.S., find a free helpline at findahelpline.com.
