I'm inlove with my ex boyfriend of almost a year. He was my first love, kiss & everythinq else.. he was the jealous type that didn't want me talking to other boys cause he had trust issues. He would always be the one to break up with me, he a jock, a football player that has groupies every were.. but gets mad at me if anothet boy even looks at me.. i've been through so much stuff with this boy. He has anger issues so when he gets mad he say stuff that he don't mean & it hurts my feelings.. we are still friends & yesterday he got mad & said I don't love him no more cuz i didnt even call or text him... I love this boy so much, we said we wouldn't evereave each other.. thats why im still by his side. He has mixed emotions ( bipolar ) bit he do me wrong sometimes, i said i'll never leave him but I feel like he need me & he be pushing me away, i dont wanna give up on him but im the one constantly getting hurt.. i cant move on so don't tell me to do that.. i just need something else to say or do, he feels like nobody loves him cuz his mom & sister do him wrong, he moved in with his dad yesterday.. he talks to other girls now also.. he expects me not to leave cuz I promised that i'll always be there for him no matter what... What shall I do.?
