Roommates

Hm, sounds like a rough situation.

I would also advise moving out. You have gone through a.) talking peacefully and firmly, as well as b.) repeating a.) but not so peacefully and firmly. You could resort to 'mud slinging' in which you begin giving him a taste of his own medicine, but it's doubtful that will help.

Maybe though you can start to do (or not do) things that would annoy him. Then say, 'I will do X (or not do X) if you will (or will not do) Y'. Most likely, it will result though in him being ultra pissed but it MIGHT get him to do things (especially if you only clean your dish and whatever tools you need to make food). Of course, keep in mind that this will only tense things up even more and whatever little he does do he might just do that satisifies him.

Jam it back in, in the dark.
