How can I stop thinking about my ex?

The best way would be to keep busy. Clean the house, go out with friends, or just watch movies or T.V shows.

Make yourself busy. Love yourself more. Do something you've always wanted to do (any kind of activity). Surround yourself with people who love you and bring the best in you.

If you still think about them.. you still love them.. you can only get over them overtime. try staying active ... and hanging with friends

Try picking up different activities and hobbies best way hands down! Why? You will be distracted, moving on, and enjoying yourself in the process!:)

you can stop thinking about your ex by doing alot of other productive stuffs like going out with your close friends, watching your favourite movies / TV shows, reading your favourite books, listening to your favourite artiste, sleeping, cycling, play your favourite games, eat, chill. there's so many things you can do! but i have to say this, it wont be easy to just stop thinking about your ex straightaway. it takes time, but it'll be worth the amount of time taken just to stop. show him/her that you're better without him/her! :)

I recommend spending your time with your family and friends. Keep yourself occupied and avoid doing things that reminds you of him :)

Your best option is to stay busy. Whether its through school, friends or work, I've always found staying busy to be the best remedy.

Reading, spending time w/friends, exercising. You can join a club/s, learn new languages, watch T.V.

I think you need to find activities that keep your mind distracted from the ex, and when there is a thought of your ex, be conscious about it, feel the feeling and acknowledge the emotion, and let the thought pass like clouds. This is a form of meditation i learnt.

Engross yourself thoroughly in an activity or hobby of your choice.. I love cooking so I spent hours searching for different recipes and trying different techniques.. I kept myself occupied by multi-tasking.. Helped a lot :)
