My W and I have been married 10 years together 12. We have an 8 year old daughter and in December of '10 she said she wanted a divorce. She has bi-polar and borderline personality disorder (diagnosed two weeks ago). Up until two weeks ago we were still communicating and being intimate despite her affair. Now she has completely cut me off and said that we can never be together again because she has tried to will herself to have feelings for me for at least 5 years now (we were lucky to have intimacy once a month during our time together). She is now completely committed to the other guy and believes that they are head over heals in love and that he is the person for her. She has not accepted any kind of responsibility for anything since she started seeing him. Now that she has cut me off and said that she is certain that we can never be together again and will be getting divorced, I am at a loss. I love her with all my heart and miss her every day and still want to spend the rest of my life with her but I dont know what to do to get her back, if it is even possible to get someone back that says they havent had feelings for you in over 5 years.

Please help me get my wife/best friend back and be a family again.
