I can't stop thinking about my ex. What should I do?

Try to distract yourself. Listen to music that will not make you think of them, happy songs, go on a run, read a book, play a game, hang out with friends. With time will come forgetting them.

You should do something that takes your mind off of it. For example, something you enjoy doing. I enjoy being with my friends and having as much fun as we can. Time heals the heart, you just have to move forward.

What you resist persists on the level of mind. Let the unwelcome thoughts in, have a coffee with them, and you'll find that they leave you quicker. Cord-cutting (a new age process) can also help.

Keep busy. Keep busy. Keep busy. Thats what got me through my breakup after 5 years. If you dont keep busy your mind is going to wander back to your ex.

Better think about yourself then! Once you start thinking about you, Your mind will eventually stop thinking about your ex. Better Move on and let the other person too. Just be Happy :)

From my experience, it's going to keep nagging you in the back of your mind, but keep focusing on moving on. Realize that time doesn't wait for anyone and overcome the thoughts your been thinking.

you should do something that makes you happy that ALSO makes you forget about your ex. For example: Go for a bike ride, hang out with friends, go to the movies, tell yourself that he wasn't worth your time and you deserve so much better :)

Think about yourself first and your with . It's ok to have flashbacks of every now and again . But your ex is your ex for a reason

It is very natural to think about your ex. In the situation of leaving because the couple didn't connect, it is ever so incremental. In situations where you were abused, you will find it more bashful than the previous stated situation. In situations where you were ignored, longing for someone is a repetitive action you were doing so it's in the norm. If you fill your time with other things, thinking about your ex is not a problem. First, try with friends. Second, with the internet, Thirdly, you can play video games or something solo. Anything that involves brain activity is good.

You should move on. You are a good person he/she doesnt deserve a persone like you. They are not worth it.
