There is really no way to explain away or understand why your husband did what he did. Each of us is different, those of us dealing with bipolar don't fully understand those without it, either. I think a better question for you is why you want to know. What is it that you need to know to make sense out of what you need to do, how you need to react to it for yourself. Can he really believe what he is saying? Yes. I was diagnosed when I became so disconnected from reality that I couldn't tell if I was awake or asleep. Literally. So, this isn't about him. This is about you. I wish you the best of luck. This isn't an easy thing to work through. I know I work very hard every day to keep my life together for the people who love me. They will never understand that statement. You may not either. Whatever decisions you need to make for yourself and your family have to revolve around your tolerance for things and situations that are traditionally intolerable. Bipolar is not mood swings. Bipolar is much more.
