He treats me like shit, but he is comforting to me. why?

He was my first ever boyfriend and he’s been the only male in my life really. I’ve told him every single thing in my life. I hate myself when I’m with him & I hate my life even more when I’m not with him. I literally feel so aimless.

He told me I would never find anyone better than him and then I tried to go on a few dates but all I want to do is talk to him. We don’t even have anything in common, he acknowledged it, it’s just trauma bonding I guess.

Has anyone else ever dealt with this?
