Why You Can’t Let Go of Someone (Even When You Know You Should)
Sometimes the hardest heartbreak is not the one that ended clearly but the one that stayed emotionally unfinished and where you know, deep down, that this person is not giving you what you need.
If you are stuck on someone and cannot seem to let go, even though you know the relationship is not right for you, there is nothing pathetic or shameful about that. There is usually a reason. And once you understand what is happening psychologically, it can begin to feel less like a personal failure and more like a pattern that makes sense.
When Heartbreak Becomes More Than Heartbreak
After the end of a difficult relationship or attachment, many people expect themselves to just “move on”. So when they find themselves thinking about the person constantly, checking their phone, replaying conversations, analysing mixed messages, fantasising about what could still happen, or feeling unable to fully detach, they often judge themselves harshly.
They might think:
Why am I still like this?
What is wrong with me?
Why can’t I just let this go?
But in some cases, what you are experiencing may not just be heartbreak in the ordinary sense. It may be limerence.
Limerence is a state of intense emotional preoccupation with another person. It often involves intrusive thoughts, longing, idealisation, emotional dependency, and a powerful need for the other person to reciprocate your feelings. It can feel consuming. It can feel euphoric at times and devastating at others. It can leave you emotionally dependent on the smallest signs of contact, warmth, or hope. And because of that intensity, many people mistake it for deep love or believe that the strength of their feelings must mean the connection is uniquely significant. But intensity does not always mean security, compatibility, or emotional safety.
Why It Feels So Hard to Let Go
One of the reasons limerence can feel so powerful is that it often thrives on uncertainty. When someone is inconsistent, emotionally unavailable, hot and cold, or only intermittently responsive, the attachment can become even stronger. Not because the relationship is healthy, but because uncertainty tends to activate the mind in a very particular way. We become vigilant, scan for signs and look for meaning in crumbs. We hold on more tightly because the outcome feels unresolved.
Psychologically, this can create a pattern similar to intermittent reinforcement, where unpredictable rewards keep us emotionally hooked. If someone is occasionally loving, attentive, reassuring, or emotionally available, those moments can carry enormous weight. They can make us feel hope again, relief again, chosen again and that unpredictability can make it even harder to walk away. It is not that you are weak, it is that your nervous system has become caught in a painful cycle of longing, hope, loss, and relief. That cycle can feel addictive.
The Link Between Limerence and Low Self-Esteem
This is where low self-esteem often enters the picture. For many people, limerence is not just about wanting the other person. It is also about what being wanted by them seems to mean. It can start to feel as though their attention, consistency, or commitment would finally prove something about you.
That you are enough, that you are lovable, that you were worth choosing
When self-worth feels shaky, external validation can become especially powerful. The emotional stakes become higher. Rejection can feel more than disappointing. It can feel like confirmation of your deepest fears about yourself. So you may find yourself holding on not only to the person, but to what they represent. The hope of being chosen, feeling secure and that this relationship might heal something much older.
This is part of why letting go can feel so painful. It is not always just the loss of the person but the loss of possibility and the loss of the version of you that finally felt enough.
Often, what makes this even more painful, is that you may already be chosen in other ways- by friends, family and people who show up and care consistently. But when one person does not choose you in the way you hoped, it can become the only thing that feels like it matters. Your attention narrows, your focus fixes, and it can begin to feel as though one person’s choice defines your worth, even when there is evidence elsewhere that you are already valued and wanted.
What Limerence Can Look Like
If you are experiencing limerence, some of the following may feel familiar:
* Constantly thinking about them, even when you do not want to
* Replaying past conversations or interactions
* Checking your phone repeatedly
* Searching for hidden meaning in messages or silence
* Feeling intense hope after small signs of warmth
* Feeling crushed by distance, ambiguity, or inconsistency
* Idealising the person despite clear difficulties
* Struggling to focus on yourself, your life, or other relationships
* Feeling ashamed of how much emotional power they seem to have over you
If this is you, please know that you are not alone. Many people go through this, particularly after relationships that have felt emotionally confusing, inconsistent, or unfulfilled, and shame tends to make it worse. Shame keeps you silent, makes you think you should be over it by now and stops you from understanding what is really happening. But this pattern is understandable and it can be worked through.
What Keeps the Cycle Going
As painful as limerence is, there are certain things that can unintentionally keep it alive.
* Repeatedly checking their social media
* Re-reading old messages
* Imagining future reunions or conversations
* Mentally replaying what went wrong
* Looking for signs that they still care
* Keeping contact going “just a little”
* Using each new interaction as evidence that something may still happen
These behaviours are understandable. They usually come from a wish to soothe uncertainty, reduce pain, or stay connected to hope. But in practice, they often keep the attachment activated.
They keep the person psychologically present, the fantasy alive and stop the wound from closing.
That is why healing often involves doing things that feel counterintuitive at first: creating distance, reducing exposure, and stepping out of the loops that keep the person at the centre of your inner world.
How You Begin to Get Over It
Getting over limerence or painful heartbreak is not about forcing yourself to stop caring overnight. It is about slowly withdrawing emotional energy from the cycle and bringing it back to yourself. It is about understanding that healing is not just about getting over them but also about strengthening your relationship with you.
What helps usually includes a few things.
* Recognising the pattern for what it is, rather than romanticising the intensity
* Reducing behaviours that keep the attachment active, such as checking, replaying, or reaching out
* Allowing yourself to grieve the reality of what the relationship was, not just the fantasy of what it could have been
* Becoming curious about what this attachment was touching in you emotionally
* Working on the deeper beliefs underneath it, especially around worth, rejection, and being chosen
* Turning attention back towards your own life, needs, values, and relationships
* Learning that your worth does not rise or fall based on one person’s availability
A big part of this process is learning to tolerate the anxiety that comes with letting go. When you stop checking, stop reaching out, or stop feeding the thoughts, there is often a surge of discomfort. Restlessness, urges, a pull to go back to what feels familiar. This is not a sign that you are doing something wrong but a sign that your system is adjusting.
Rather than trying to escape these feelings, part of the work is learning to sit with them, to allow them, and to let them move through you without acting on them. Feelings, even very intense ones, are temporary. They rise, they peak, and they pass. And each time you allow them without going back into the cycle, you are weakening the hold it has on you.
This work can feel uncomfortable and very painful at first. Letting go of limerence often means letting go of hope, fantasy, and the emotional highs that came with waiting for things to change. But on the other side of that is something much more solid- peace, clarity, self-respect, freedom and perhaps most importantly, the chance to build a life that no longer revolves around whether someone else texts, chooses, returns, or finally becomes who you needed them to be.
A More Compassionate Way of Seeing Yourself
If you are in the middle of this right now, try not to reduce your pain to “I’m obsessed” or “I need to get a grip”. Usually, there is something much more tender underneath- a longing to feel chosen, a fear of being left, a deep ache around worth, a hope that love might finally feel safe.
And often, a lot of anxiety in the body, a tightness in the chest, a constant sense of unease or anticipation.
When you see it through that lens, the goal stops being self-criticism and starts becoming self-understanding. You do not need more shame. You need honesty, support, boundaries, and compassion.
A Final Thought
If you cannot let go of someone, even though part of you knows you should, it does not mean you are foolish, dramatic, or broken. It may mean that this connection has become tied up with deeper emotional needs, vulnerabilities, and beliefs about yourself. That is painful but it is also workable. With the right support, it is possible to understand the attachment, loosen its hold, and rebuild a sense of self that feels steadier and less dependent on someone else’s attention or inconsistency.
If this resonates with you, therapy can help you explore these patterns in a safe, compassionate, and non-judgemental way. I offer online CBT therapy for adults experiencing low self-esteem, overthinking, relationship difficulties, and anxiety, both in the UK and internationally.
