I am not sure you can get her to understand. I don't know much about how the bipolar mind operates, but my hunch is anything that is brain-based is going to be extremely difficult to deal with. She may truly not remember, and she truly may not feel remorse, because in order to feel remorse you have to have a sense that you have done something wrong. Also, she doesn't have to take responsibility for her actions because you are still around and taking it. So there isn't much motivation for her to change. The sad thing is because you and her have a child together, she has a hold on you. I do hope very strongly that you are using condoms and not just leaving birth control up to her or you may have another child on your hands.
I have a former neighbor who comes around every now and then. She can be pretty nasty and rude and she is well aware that she is being nasty and rude. She's actually quite proud of it. That's who she is. Oh, yes, she's bipolar. Once, in an unguarded moment, she let it slip that she was and I said that I had suspected as much, which surprised her because she thinks she is pretty good at pulling the wool over people's eyes. She sits there and brags to the rest of us about how she has done this one and that one dirt, but they deserved it because . . . (and I won't repeat the rest of it, but you get the drift). One day I told her point blank that life was much too short to spend it hanging around unpleasant people and I got up and left. Her mouth actually dropped open in an O. I don't think anyone had done anything like that to her before. No, it didn't change her. It just gave her one less target.
That's not to say that bipolar isn't a legitimate medical condition, but my experience with these people is that they are bad news and that they often choose to behave the way they do. .I am sure that there are probably many bipolar people who successfully take their medications and can function around others with a minimum of drama. Unfortunately it is the ones who thrive on drama and chaos who give bipolar disorder a bad name. Is there a bipolar support group in your area? They might be better able to help you deal with your girlfriend.
