I agree it may be a good idea for him to stop staying overnight. You and S will get break from drama and that is good for you and S. H's attitude MIGHT also improve. He can't handle the stress of doing this every day because he already has mood issues. Men on this board claim men need to go to their cave to repair themselves. If that's true, an improvement in the sitch could come from him getting space. Continuing as is also will not fix anything. Maybe don't engage him in power struggle about sleeping at the house. It seems like it will blow up on you. Sorry you are having such a rough week. This sounds like a very stressful situation right now. You have the power to stop the fight cycle even if he tries to continue it.
Please tell yourself he is not the last man in the universe who will love H4L whichever way this goes! You make friends easily. And people like you. You have a good sense of humor and I can tell you would be fun to spend time with.
