I've been with my boyfriend 6 months he's cheated already and we can fight really bad I love him but not like I used too. He's warring me down and I'm starting feel like nothing I know this all wrong but I just can't find the strength to leave please help!

I know how hard it is to leave some body you love or care about .but if your not happy or not yourself . That's not good for you .and if your fighting that's not healty .now I don't want to say this to be mean but you could do a list of cons an pros and ah which one has more or you could live in a realationships where nothing is fun any more for u .do I feel like your on a roller coaster your feelings change ing because you love him but you have you need to leave? Kind of thing
