I just joined today bc i wanna keep from texting my ex. We broke up on good terms and its rly sad to stay away from each other qhen we both know we were the best we had and only ever had good memories. We had to break up because i wanted to focus more on my studies and my future, but it backfired bc hes all i ever think of now. Has anyone else gone through this? Any advice on how to fix my mindet or anything regaurding a breakup? Maybe ot seems minor but this is the biggest thing thats happened in my life so far
Some details , i still have him added on text app bc im worried he might h*rm himself, so i dont know if i can block him, maybe ever. Idk😭
He was my best friend but i felt like i lost myself so im trying to regain my own life, but everything i do, i wanna tell him about
I’d possibly recommend just keeping your distance for a while. If it was a good relationship and is meant to be , it will work itself out in the future. Or if you have the distance for a little maybe you two can be friends. Break ups are hard especially harder I think when you leave on good terms because there isn’t all the bad stuff and reasonings why to hold onto. But I think if you made it to this point it was the right decision. Focusing on you is never a bad thing and in a relationship you should have the room to grow individually so if you feel the need to do that solo you should!
As for him, I hope he has other people to help him and support to lean on if he has stated potentially harming himself.
Best of luck to you on this journey ! Time is a good healer for the heart 
Welcome @Ttt to a supportive community. Congrats on identifying the unhealthy thought patterns around your ex. Id write down a list of why you should keep your distance (i.e. grow stronger personally and less dependent on them, focus on your other priorities, unhealthy patterns) We can get stuck in unhealthy thinking. Im not quite sure how you break that pattern, maybe some other member could offer some other solutions.
Just glad youre reaching out
It just takes time
