So I'm assuming, based on what you said to me that it is not an option at all (for whatever reason).
What I am saying above is that if you are staying, you don't have an out, you do actually just have to put up with it.
I mean there are obvious things where if he starts on a rampage you just take the teens and the three of you go sit in a room (door locked) somewhere together away from him. If he then is the type of person that would follow you all and break down a door if it's locked, I see no way around that. So yes, there is no solution to the current situation.
You mention he attacks you verbally and if you won't play he turns to the kids. You have tried everything, as you have mentioned and none of it has worked. So short of leaving, do you see any way to stop him?
He won't change and you won't change (the situation). You are at an impasse.
