Need Advice

Well I hope that everyone had a very blessed and wonderful Thanksgiving. I seem to have the curse of making very bad decisions when it comes to picking a partner. She got us kick out of our recent apt right on Halloween so that ruined that and then I didnt have a Thanksgiving either because she was bitching and arguing all day so that was ruined also. And there is so much more she has done to me physical and emotional abuse and still continues to do it. Her family doesn't invite her anywhere because of her attitude and her drinking plus she talks to anyone and kind of way, she so spoiled everyone including me always let her get her way. I love her so much I do but I don't know what else to do to help her. I know that shes a good, big hearted person. I also know that she knows she hurts me but yet she continues to do it and she so bi-polar let me tell you but she still don't get help. Its like I have to do everything for her because. You know what I don't even know why. I guess that's how stupid I am. Every time I try to get my space from her she always seem to draw me back in. I thinks she enjoys it because she know that I am going to give in please help me and trying to figure out what to do I really need advice thanks.
