How can I stop thinking about my ex?

How about instead of thinking about this person, write it all down in your journal. Every time you have a thought, if you are near some paper, write it down. If not, wait until you get home and write it all down. Keep doing this until you are able to move forward in your life.

You have to surround yourselves in things that you enjoy. Change up your everyday routine make it interesting. Otherwise everyday you will have an empty feeling and your ex will take up your mind every second of everyday.

Think of our live’s like books, some people come and go. But just because their gone, doesn’t mean it’s over. It just means their part in our story is over. Just another chapter. It’ll be hard to get over them but it’s not impossible.

Try to focus your attention on something that you like. As in you can engage in some activity which helps you forget problems.

To stop thinking about your ex, you need to start keeping yourself busy. It can be hanging out with friends, finding a new hobby, joining a gym or any class, a new tv series, etc. Because remember an empty mind is a devil's workshop. Focus more on yourself- your health, your goals. Do what makes you happy and content :)

Before anything else, you have to allow yourself to grieve. Watching our relationships end will never be something we can just get over after ten minutes, and that's okay. Cry in your bed, cry in the shower, cry with your friends. Allow yourself to sit down on the couch and feel nothing but absolute sadness. Don't try to skip this stage; it's the first step towards getting over someone. After you're done mourning and crying and feeling sad, however, you have to take some more proactive steps. Throw away all that reminds you of your ex, return everything that belongs to them. Delete pictures, throw away the gifts (or if you're not ready just hide them somewhere you can't see), get rid of anything that even slightly reminds you of them. Unfollow them on social media, at least for now (out of sight, out of mind). After you do all of this, it's time to focus on yourself. Get a new haircut, clean your whole house, adopt a new habit, start exercising, buy some new clothes or sell/donate the ones you don't like. Hang out with your friends (I would not advise drinking or doing drugs just to try and forget someone), whether it's pizza night or going to a club or both. Just make sure you're having fun with people who care about you. It's all a matter of keeping yourself busy and doing things for yourself; that's what moving on with your life really means. Try that art class you always wanted to take, try a new workout routine, set new goals. If you try to forcefully not think about your ex, it will have the exact opposite effect. When they come to your mind, take a deep breath and just let that thought go; there's not a lot of things you can do. It's in the past. Focus all of your energy on your own stuff and after a while you'll realize that you hardly ever think of them anymore.

Try doing things that you love and focusing on experiences and yourself. It's alright to think about your ex and the memories you share, but don't focus on just that. Focus on growing yourself. Find something that you love, either sports, books, friends, religion. What makes you happy is what is important.

Many ways, however, some people deal with things differently so we'll see. But...usually, do things that you enjoy and feel comfort in. Do things that are the complete opposite of what it was like in the relationship, do things that maybe your partner hated but you loved. Something along these lines

Thoughts aren't something easily controlled, however that doesn't mean you don't get to choose how you see your experiences and memories with them. It's not necessarily bad to think about your ex, though those images can be sour at first, with time and compassion they can develop into something to reflect instead of dwell upon.

firstly, focus on the word 'ex' and understand that it means he/she is not in your life anymore and for you to be happy, concentrate on your present. i know it is hard but you have better things coming your way. try and avoid places and memories that trigger you to think about it.
