I think a large part of the heartache, holdings hope, is that you don't comprehend your husband's situation exactly. You say, "Wife of Husband with Ultradian Bipolar 2 Disorder & OCD (currently unmedicated)." He's actually pretty heavily self-medicated from your description--on alcohol, I assume. He may well be an addict, which pushes the bipolar & OCD issues way over the top.
In my opinion, you both need to face up to and deal with the addiction. He's already got legal issues from it, certainly emotional/mental, and possibly medical.
I'm very concerned about your kids, who may already be scarred for life. Please--you all need help with this.
