wpasierb,
I was reading your first thread, and you got a lot of good advice and support there.
Could you and your daughter simply leave and go to your parents' house? Would they take you in? I don't see that you have a lot to lose at this point. He isn't organized enough to wage any kind of legal fight for his daughter, and she is in that hell right there with you. If you aren't willing to leave, yourself, could she maybe go stay with them for awhile?
Death from cirrhosis can be sudden, but it can take a long time.
I'm sorry you're in this situation, but your own health and your daughter's well-being are at stake here. I think those trump his slow suicide.
