Wondering how to stop thinking about someone?  And why is it you can’t stop thinking about them when they broke your heart, or made you crazy?

Is there something wrong with me?

You are far from alone in being unable to stop thinking about a romantic interest, ex friend, or crush.

A research overview on addictions drawing on data from 83 studies found that love addiction was thought to affect up to 26% of the adult population. 

Why can’t I stop thinking about him or her?

We live in a society that encourages unhealthy approaches to relating. Social media, films and television present us with an endless parade of addictive behaviours that  are sold as ‘love’, and codependent entanglements that are called ‘friendship’. 

These false ideas won’t have too much of an influence if we grew up learning healthy relating from the adults around us and had a safe, secure childhood. We’ll simply know better.

But we might fall for these damaging ideas of relating if we had: 

So the first step in how to stop thinking about someone is to understand what the real issue is (and it’s rarely related to the other person). 

1. You never learned what healthy relationships are. 

‘Modelling’ refers to the way children learn behaviours from what they see around them. Examples of poor modelling would be parents or a parent who:

  1. always fought than made up, teaching you love is intense and wild
  2. or were dishonest, with one endlessly obsessed on where the other was, teaching you to love is anxiety and overthinking 
  3. had endless short and intense relationships that left them broken and obsessed afterwards, teaching you that love is obsession.

2. You have attachment issues.

What doesn’t change as easily, however, is the belief about love we learned from our direct relationship with our primary caregiver.

If you were only loved if you were ‘good’, or had a moody, unstable parent or guardian who only loved you when they felt like it? Or not at all?

Then you are likely to  grow up into an adult with what are calledattachment issues’. 

If you are unable to stop thinking about someone, you most likely have anxious attachment’. You might push and pull in relationships to get a break from the anxiety they cause you. But if the other person leaves, you panic. 

3. You are a love and relationship addict. 

  • When things were good with the person you can’t stop thinking about, did you feel so great it was like you were ‘high’?
  • And when you fell out or fought did you feel so low you could hardly leave the house?
  • Or do your thoughts about this person tend to sabotage the rest of your life ?
  • Affect your work or school performance, leave you so distracted you forget important things, affect your sleep and eating, even?

Then you might have a problem with one of the different forms of relationship addiction, which can be love addiction, romance addiction, or even just straight up people addiction.

4. You lived through childhood trauma. 

Trauma in our childhood, like sexual abuse, destroys our sense of self. As an adult we can have such low self-esteem, we latch on to others as a way to feel we have value, and become addicted to their attention.

Or we have what is called ‘trauma bonding’. We are so used to being a victim it forms our identity. We unconsciously seek out the highly destructive relationships that are our comfort zone, and become deeply addicted to them, even as they destroy us.  

5. You have borderline personality disorder.

More accurately calledemotionally unstable personality disorder’, irt means that you deeply fear rejection

The tailspin feeling abandoned sends you into can include obsessing on the other person, and doing whatever you can to manipulate them back.

How to stop thinking about someone

It can be helpful to treat your obsession with the other person like an addiction.

1. Recognise that thoughts are thoughts, not reality.

If you were a recovering drug addict, you would quickly question any thought about how great the drugs were, and how you should go back to that lifestyle.

When it’s a person we can try to convince ourselves it’s different. It’s not. You need to question each and every thought you have about them. 

Your obsessive thoughts about the other person will often be false, romanticising what happened, or giving you dishonest beliefs like you ‘can’t live without them’. You can, and you will. 

2. Don’t give the thoughts energy.

Yes, that means stop talking about it with everyone and anyone who will listen. Endless talking just feeds the addiction as you gain attention for playing the victim

And stop hanging around with people who profit from the fact that you are addicted to someone. Perhaps they are a person addict too, so feel less alone. Or they take energy from seemingly ‘helping’ others. 

Instead, talk to a therapist. The difference is that a therapist doesn’t leave you to fall into a black hole of negative stories. They are highly trained at asking just the right questions to help you see new perspectives you have missed and find your way forward.

TRY THIS: Journal with intention, such as writing out all your thoughts without editing yourself, and then ripping the pages up after. Or find a private place, set a timer for five minutes, and make yourself talk about the other person to the end of the timer. If you are brave, record yourself, then play it back and have a listen. 

3. But do give the feelings attention.

Often we have obsessive thoughts as we are misusing our emotions. Instead of just feeling them, and accepting what they are trying to tell us, we hide from them with obsession, anger, rage, and grief. If we actually work with our feelings instead, the crazy thoughts can pass. 

TRY THIS: The next time you find yourself obsessing on the other person, find a quiet place, sit still, and close your eyes, applying mindfulness to the situation. What is it you are actually feeling at this moment? Is it rejection? Loneliness? Rage? Just sit with that feeling, quietly, not judging or examining. What does it feel like? Is it hot, cold, heavy, dizzy? Where is it in your body? Let it mutate into other emotions if it wants to, like sadness. 

4. Practice replacement.

Baking, exercising, a new job… the point here is to find a healthy replacement, and to throw yourself into it. 

TRY THIS: Find one of the dreams and goals you let fall by the wayside when the other person came along. Sit down and break down al the steps reaching that goal will require. Use the SMART model. Then schedule into your diary all the first steps and get going. 

5. Seek therapy for relationship addiction.

Clinical hypnotherapy helps breaks the hold the other person has on your mind.

Cognitive behavioural therapy (CBT) helps you recognise and question your thoughts, replacing them with balanced thinking instead.

Compassion-focused therapy can help you build your self-esteem and release your anger. 

Trauma therapies are advisable if you lived through difficult experiences (other forms of therapy can sometimes backfire). And if  think you have borderline personality disorder, then it’s important you get  try a therapy that is created to help BPD.
