This girl sounds very much like me also. I have been angry at my husband, and have treated him unlovingly. I've never cheated, but that's cause I have five kids and never get out of the house. I took all his saying nothing as not caring, and when he said something I blew up. I would write terrible e-mails to his family and parents. I've been in therapy for 8 months now. On meds., and things are just starting to get to normal. She needs to discover empathy for your and your family, which will only come with therapy, and meds. It took me 6 months to get over the anger, and see that I have made them suffer. But I was abusive, and angry as well. All these things she is doing is making he symptoms worse. Too much change not enough stability, and structure. Blowing money and hyper-sexuality can be apart of this, but for me...I'm on meds, and it takes all of my libido away. So I feel nothing. I agree she's not taking her meds either, nor is she with the right therapist. If she is on her meds she's not taking them. Does she do drugs? Street drugs extascy and cocaine can make it worse. Get the book that was mentioned. It will validate you. I just bought it Monday for myself and my family. I'm so glad it was mentioned. I read the first few pages, and it gave me more understanding and empathy. To go or not to go? I think she really needs to accept she needs help, and I don't thing she will until she crashes, and then she'll come to you again. Sigh.... I don't know how you put up with the cheating. But I think she thinks you'll put up with anything at this point. So sorry for you.
