You aren't married to this woman who seems to be totally uninterested in getting help. I seriously doubt she is taking her meds. Your relationship is fast becoming codependent and is not healthy for either one of you. I say cut your losses and let her go. There is no future with a bipolar who refuses treatment, but more of the same things you have experienced over and over. You wouldn't take the kind of abuse she is dishing out if she WEREN'T bipolar...don't let her use it as an excuse to abuse you any more.
