I am new here too. I have been living with the bipolar diagnoses for 18 years. The treatment you are receiving from your husband sounds very similar to the way I treated my first husband. I had a manic episode that involved delusions and became convinced that I had to divorce my husband. He is a very kind but naive person and could not comprehend what I was going through. Unfortunately the divorce proceeded and we went our separate ways. I got medication and therapy and felt a deep sense of regret over the loss of the marriage. I can say that medication completely altered my frame of mind. I believe if your husband is properly medicated he may alter his behavior.
Ultimately, you have to take care of yourself and you sound like you are in a great deal of pain. I hope that your situation is settled for the best of both of you.
