breaking up with bipolar girlfriend

My girlfriend is bipolar and I do not know if I can speak with her again?
My girlfriend who unfortunately have fallen in love with, has an attitude that I know not her fault because she is bipolar and I love her and everything, but theres two sides of it, sweet, and a serious side and evil that attacks on me at one point and I really makes crazy, but I bite my tongue when I am upset. Should cope with it? She is truly amazing and the first girl I've ever liked, but I have no idea if I should talk with her about her because she can get angry and break me. What do I do?
Opposite her is not going to change things, that's just what is due to his illness, and if you feel there is too much to handle, maybe it's better to leave for his own sanity. You have to think too much of your own happiness.Good luck.
