I am one, and you will ultimately find he has taken you hostage within a mental-emotional spider web you cannot escape if you do not let him know his being bi-polar is never going to be accepted as an excuse for wrong behaviour...and then stick to that even though bi-polar might at times at least partially explain his personal challenges in the relationships department. When the judge asked my second wife and I why we wanted to divorce, we told him we were incapable of being together without one or the other of us being hurt...and we were talking about more than mental-emotional harm. She was done with my abuse, and I still had no ability to treat her properly at all times. We re-married later on and have now been happily married for many years, but we both understand it is never okay for me to treat her disrespectfully and she never dances to my tune just because I happen to be bi-polar.
