One of the things I had to get past in my recovery was the all-or-nothing, black-or-white thinking.
In one thread, you have gone from calling work for him, and empty threats, to divorcing and losing your house. How about taking some small steps first? Like no more calling work for him. Like no more staying up all night worrying about what he's doing. Like no more saying you're going to leave when you have no intention of doing so.
You didn't get into this situation in a day, you are not going to make it better in a day. Think smaller, it's more doable.
