I once again broke up with my ex, that happened 3 months ago, I'm on a new relationship again which it was too soon tbh. It's the second time that I start a new relationship and suddenly I start regretting that I broke up with my ex in the first place. 

It comes back to her every time, it seems like I am trying to replace her. She knows that I'm bipolar and rightfully so she won't trust me because I'm a mess, she doesn't deserve everything I did with her. We both have feelings for each other but I don't wanna hurt her again, I need to be certain that I'm not hypomanic or doing it from a selfish place. 

It all started when I went maniac and started to think that I could be better, that I should be fuck all the girls that I wanted to. Then I regret doing it, start dating and then I regret dating and I start to realize that I miss her. 

It's happening again I need help.
