While you undoubtably wish to stick it out and be there through thick and thin, you have minor aged children, and they come first. I'm sorry, but they do. You would not leave them with a mentally baby sitter, so don't leave them alone with their father. Next time he throws you out, get out, stay out and tell him you aren't coming back unless he is willing to get help himself.
Some of my favorite people on the planet are seriously mentally ill. I understand your relunctance to leave. If you can get him into a group home situation where you can visit him daily, that would be best.
