As someone stated earlier, thank goodness you have a therapist right now. I cannot really imagine what you are going through. My husband and I have both said we wanted a divorce in the heat of the moment. I say it to him because I believe he deserves someone better. He says it to me because he thinks he makes the wrong decisions which go against my best interest. Leaving you just because you are bipolar is not a good answer. I hope he's able to be more honest. When you love someone, you don't leave them for a reason like that.
