How do I stop thinking about my ex?
Short answer
You cannot stop the thoughts by deciding to, which is why the effort makes them worse. What works is reducing the supply and giving the mind somewhere else to be: mute rather than dramatically block, stop checking, put the photographs away for now, and end the late-night rereading of old messages. Then let the thoughts that still arrive pass without arguing with them. For most people the constant replaying fades over several months as the days fill with things the other person was never part of.
The replaying is one of the most exhausting parts of a separation, and one of the least discussed, because it feels slightly humiliating to admit that someone occupies your head all day.
It is not a sign of weakness or obsession. It is what minds do with an unresolved attachment and an unfinished story.

Why the thoughts keep coming
Two mechanisms drive most of it. The first is attachment: for years your nervous system treated this person as your point of safety, and it does not update that overnight simply because the legal position changed.
The second is unfinished narrative. The mind is relentless about incomplete stories. If you do not know exactly why it ended, or you never got a satisfying explanation, it will keep re-running the tape looking for the missing piece — which is why the replaying is worse for people who were left without warning.
Suppression backfires for a well-documented reason: instructing yourself not to think about something requires holding it in mind. The aim is not silence. It is lowering the volume.
What actually reduces it
Cut the supply, quietly
Mute or unfollow rather than making a dramatic gesture. Every check restarts the clock, and checking is usually habit rather than curiosity.
Stop rereading the messages
Archive the thread. Late-night forensic reading of old conversations is the single most reliable way to lose an evening and learn nothing.
Give the thought a time slot
Fifteen minutes a day, deliberately, in daylight — write it down, then close the book. Scheduled thinking reduces intrusive thinking surprisingly well.
Move the body
A walk interrupts a loop faster than reasoning with it. Not because exercise is a cure, but because rumination needs stillness.
Change the physical cues
Rearrange a room, change which side of the bed you sleep on, take a different route. Cues trigger the loop before you notice.
Let the thought finish
When one arrives, note it and carry on with what you were doing. Fighting it gives it a second life.
The special case: contact you cannot avoid
If you are co-parenting, no contact is not available to you, and advice built on cutting someone off entirely can feel useless.
What helps instead is narrowing the channel: written communication only where possible, restricted to logistics, short and unemotional, ideally through a shared calendar or a co-parenting app. Handovers kept brief and neutral. No discussion of the relationship at the door.
This is not coldness. It is protecting the part of your day that keeps getting reopened.
You are aiming for fewer fresh inputs, not for a personality that no longer cares.
How long the intrusive stage lasts
Most people describe the constant, all-day version easing over three to six months, then thinning into occasional strong episodes that fade over the following year.
The change people notice is not silence but delay: they realise it is four in the afternoon and they had not thought about it yet. That usually arrives without ceremony, and often before they feel any better in general.
People also ask
Should I block my ex?
If there are no children involved and contact keeps reopening the wound, many people find muting or blocking genuinely helps. Where there are children, narrow the channel instead of closing it.
Why do I dream about them every night?
Dreams process unresolved material, and a separation supplies a great deal of it. Frequent dreaming usually eases along with the daytime replaying.
Is it bad to look at their social media?
It is the most common way people set themselves back. Each look supplies new material for the loop, which is why the urge feels like relief and the aftermath does not.
What if I cannot stop thinking about their new partner?
Extremely common, and almost always more about your own fear of being replaceable than about that person. Reducing exposure helps far more than analysis.
When to get more support
If the heaviness is constant rather than in waves, if you are managing it with alcohol, or if you cannot see a version of the future you want to be in, please speak to a doctor or a therapist. That is not an overreaction. If you are in crisis, contact your local emergency services.
