<human>: Sorry this is so long and any typos, iPhones suck--
I really, really love him and I can't forget the way I just left him. I went out with a friend after work and didn't let him know (my first mistake) he was blowing up my phone but it was on silent(he doesn't believe me) so I rushed home after I saw his messages. As soon as I get back he's yelling at me for being out late and having alcohol on my breath. I told him I'm sorry I didn't see his messages and he said if I want to go out drinking with people from work till 3am I should just leave, so I did. I'm only 22 I. Felt so trapped. We have a great relstionship otherwise. Tons in common and we love doing stuff together. I ended up calling my male friend to come get me. I've been staying with him since I'm pretty much homeless. I could go stay with my grandpa but i just don't want to burden him. I've thought about just saving some money and disappearing, I just feel so ashamed and evil..especially since I had sex with my friend when we were drunk and I had tried some crack that was offered and didn't expect the feeling. I was upset he was trying to comfort me. I'm scared I really fucked up when I left  my ex. When I went to pick up some of my stuff I was honest with him about what I did and I didn't expect his reaction , he started crying and freaking out. When I tried to leave he chased me and wanted to fight my friend but I was able to avoid that . I'm not sure if I made the right choice. I don't like feeling trapped when I'm so young but I do want to be with  him still. I just needed time

Could you distill the essence of the text into 1-3 sentences?
<bot>: I want my ex back but I don't think he will ever take me back how do I talk to him and fix this?? I really want our life back. Am I wrong for leaving?
