My situationship and I like to game together. He gets insanely jealous over everything I do. We're not official, but he gets mad over me hanging out with other friends and people flirting with me. Im not attractive by any means, but I do get people who ask me out and make comments. Recently, while we were gaming someone starts flirting with me. Now, he flirts in chat with other women all the time so I assumed it was fine. Someone messaged me and flirted with me, and so I flirted back (just innocent fluff stuff, them saying I was the best white fox player they've ever seen etc). He got mad and just refused to talk to me and while he says its his own problem with jealousy I dont really believe it, he makes it feel like my fault. And I know the obvious thing is to leave him, but he doesnt really have friends outside of me and he's the only person ive talked to about the abuse I've went through. I want to leave him but I think I'll just come crawling right back. I know this isn't healthy.
