Blackcat, don't wait for him to go out, he knows it's hard to find a place, so you do, the best thing is let him take his own medicine, he don't mind you at all anymore, then do the same, leave it like that, you live in the same roof but not minding to each other, don't cook for him, don't wash his clothes, but don't ask money for grocery, sounds fair???
