I also think that she is having maybe a midlife crisis of sorts. She is 40 and I am 34. I agree with the hyper sexuality. So does my therapist. I've tried to talk to her about getting to a therapist to be evaluated to see if she is manic but she hasn't been to one in almost a month. She just says "I'm not manic, you are just trying to control me and are mad that I want a divorce." to be honest her behavior is very selfish and childish. She tells the kids she is coming to see them and sometimes never shows up. The children appear to be a very low priority to her. My ultimate question is, is she ever going to realize what she is doing to her family? Is she going to come back when she is better and try to make this right? I can wait. She is worth it to me, but if its a lost cause then I need to do what is best for me and move on.
