<human>: Condense the text into a few key points

I'm 23 and my now ex is 26 years old. Emotionally though, he acts like a 5 year old.

I've been on a very tiring roller coaster this past year. My ex is bipolar and it was a very emotionally draining relationship. 2 days ago he broke up with me, for a very dumb reason. Every time we would fight or he'd "break up" it would be for the most ludicrous reasons.

This time around I feel like I should stop it here and not contact him anymore. He's turned me into another person. I've become insecure, I'm afraid to speak my mind and I don't like going out anymore. 

When I started dating him, I knew he had bipolar. He told me he had it under control and he was getting therapy for it. After awhile he stopped going to therapy and changed. It was about 4 months into our relationship and he started telling me he was gonna go out for the night and sleep with women. He'd then turn off his phone and not call me till the next day. He would always try to provoke insecurities and make me feel bad.

Anyway, even with all the mental abuse and all the mean things he did, I still loved him. I would do anything for that kid because he's just  the most amazing person I've ever met. I have such a hard time dealing with this break up, even though I know it's for the best. I'm hurt and sad because I feel like I've lost the first person I ever truly loved. I've been through break ups before, but they've never hurt this bad. I'm really lost.
