help!!

okay so i’m posting in here to rant but i also need advice. me and my boyfriend (E) have been together over a year. we moved into my aunts house when i moved out of my parents so i could go to college. We fight about every little thing, it’s bullshit. my aunt who is also my bestfriend says that the things he says such as “ i don’t want you anymore” is to just piss me off. because he is 100% in love with me the next minute. he’s never had a good relationship so i just brush it off bc i am also new to this serious relationship. i am in a sorority and he does not let me go out to any of the mixers or anything and i’ve always assumed just bc he doesn’t want anyone to hit on me. another thing is that he doesn’t believe in medications and i just recently got diagnosed with bipolar disorder and he believes that it’s all on my head and that really makes me angry bc i have tried to commit suicide in the past and know when it’s time to get help. my aunt has hinted at the fact that i might be in an emotional/mental abusive relationship. i don’t want to leave him bc i do truly love him and i can picture spending the rest of my life w him but i also do know that if we were to break up it would be really hard but i would probably go on a sex binge so i’m not too sure what to do.
