Your ex keeps showing up in your head uninvited. You’re brushing your teeth and suddenly you’re replaying that argument from eight months ago. You’re trying to fall asleep and your brain serves up a highlight reel of their laugh. This isn’t about missing them, necessarily. It’s your brain stuck in a loop, and loops can be broken. These methods actually work, but none of them are instant. The thoughts will thin out over weeks, not hours.
1. Go full no-contact
This is the one that makes everything else possible. Block their number. Unfollow them everywhere. Delete old messages and chat histories. Not "mute" or "restrict" – actually remove them from every digital space you occupy.
Every time you see their name pop up on a screen, your brain gets a fresh hit of them. You’re trying to starve a fire and leaving kindling everywhere. The harshness of it feels disproportionate, but partial measures don’t work here. You’ll convince yourself that checking their profile "just once" is fine, and then you’ll do it fourteen more times that week.
2. Purge the physical reminders
That hoodie they left at your place. The photos on your fridge. The playlist you made together. Box it all up and get it out of your living space. Give it to a friend to store if throwing it away feels too permanent.
Your environment is full of triggers you’ve stopped consciously noticing. But your subconscious hasn’t. Every object associated with them is a tiny prompt for your brain to start the loop again.
3. Label the thought, don’t fight it
Here’s the counterintuitive one. When a thought about your ex surfaces, don’t try to shove it away. That makes it worse (try not thinking about a white bear for ten seconds). Instead, just name it: "I’m having a thought about my ex right now."
That tiny act of labeling creates distance between you and the thought. You go from being inside the thought to observing it. It sounds too simple to work, but cognitive defusion techniques like this have solid research behind them. The thought still shows up. You just stop letting it drive.
4. Schedule your obsession time
Pick a window each day (20-30 minutes, not before bed) and give yourself full permission to think about your ex during that time. Obsess, replay, grieve, whatever you need. Then when the time’s up, you’re done until tomorrow.
When a thought pops up outside that window, you tell yourself: "Not now. I’ll deal with that at 6pm." Write it down if you need to. This works because you’re not suppressing the thoughts – you’re postponing them. Your brain cooperates with postponement much better than with suppression.
5. Move your body
Exercise isn’t some generic wellness advice here. It’s specifically effective against rumination. When you’re running or lifting or even walking fast, your brain has to allocate resources to coordination and breathing. That leaves less bandwidth for the thought loop.
30 minutes of anything that gets your heart rate up. Do it when the thoughts are at their worst, not on a schedule. The post-exercise window is the closest thing to a reset button your brain has.
6. Fill dead air with focused activity
The thoughts hit hardest during unstructured time. Lying in bed, commuting, showering. You can’t eliminate all of that, but you can reduce it.
Pick up something that demands actual concentration. Learning a language, playing an instrument, doing a course, solving problems at work you’ve been avoiding. Passive entertainment (scrolling, binge-watching) doesn’t cut it because your brain can run the ex-loop simultaneously. You need activities that require your full attention.
7. Write it out, then close the notebook
Journaling about your ex isn’t about processing your feelings in some therapeutic sense. It’s about getting the thoughts out of the loop and onto a page where they stop circulating. Write down exactly what you’re thinking. Be as petty or sad or angry as you want. Nobody’s reading this.
The key part: when you’re done writing, close it. Don’t reread. Don’t edit. The point is extraction, not analysis. Do this daily for a couple of weeks and you’ll notice the entries getting shorter on their own.
8. Decide it’s over and act like it
At some point, you have to make the active choice. Not "I hope I get over them" but "I’m done giving this person space in my head." That sounds like motivational poster nonsense, but the decision matters because it changes how you respond to everything else.
When you’ve decided it’s over, you stop entertaining the "what ifs." You stop checking whether they’ve viewed your story. You stop having the internal debate about whether you should text them. The decision doesn’t stop the thoughts from appearing, but it stops you from engaging with them when they do.
Intrusive thoughts about an ex aren’t a sign that something’s wrong with you or that the relationship was "the one." They’re a sign that your brain formed a strong pattern and hasn’t finished letting go of it yet. Every method here chips away at that pattern. Some days will be worse than others. But the trend line points down, and eventually you’ll realize you went a whole day without thinking about them at all.
