^^What they said.
You aren't going to change him.
I live alone and love it. You could find a room or a roommate situation that would be far better than this prison you're in.
I left alcoholics - twice: more times than that if you just count dating situations. It's not going to get better. I've also left two live-in relationships that became physically abusive. Both those times I left with my stuff while the men were at work and never spoke to or saw them again.
No regrets on any of my choices and I would do it again if I had to.
