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

Stay positive and remember your life must go on. There are more fish in the sea. You can rxclude them from your thoughts by replacing their precense with much happier thoughts!

Try doing something to get your mind of them. Listen to some good music, watch something funny or hang out with friends.

Focus your energy and your mind on yourself for a bit. Do something only for you whether it be going to a movie or getting an ice cream cone. Taking care of yourself will help with the feelings that you are yearning for

It depends on if he/she has a girlfriend. If they do, leave it alone. I've seen love die way too many times when it deserves to be left alone. If they are single, try to make time and hint if they feel the same way.

Usually ex's are an ex for a reason. So think about the reason you broke up then think about the reason they're on your mind. From experience I've found that we miss the feeling of being with some not the person.

You can't stop thinking about your ex. Relationships are often a complicated thing. Have you tried to communicate with them so maybe you could know if they are in the same situation as you?

Keep yourself from visiting social media of his/hers and try to keep yourself away from things that may trigger you to remember him/her.

Focus on yourself, find a hobby, hang out with your friends, pamper yourself. try to explore yourself more there's a lot more to life than a significant other

Try putting your mind on other things, go out with friends, maybe even try getting back out there and looking for some one new for your love life

You should stop trying to not think about your ex. Go ahead. Think about them. Think about your entire relationship. Talk to someone about it. Find a friend who has free time and just tell them to listen to everything you have to say and tell them every single detail about the relationship and tell them every single thing you've ever wanted to say to your ex. That gets all of it out of your system. Listen to music that empowers you. Sing along and dance to it. Just let yourself go in the music. Over time, you might even find someone else after you feel like it.
