Would work for cooking(but I'd rather avoid his wrath) but not for cleaning. His stance is "if you have a problem with things being dirty why don't you clean them?"
Apparently he'd be fine living in a dump.
It's be a shame if his girlfriend saw the mess he'd live in if you decide to move out. One day she might have to clean up after him.
Meh, could always move in with me. Three ground-rules: 1- I smoke my stinky cigars and you say nothing. 2- I get drunk sometimes, deal with it. 3- ALL THE GODZILLA MOVIES, THE HORROR MOVIES AND STUFF RELATED, STAYS.
And yes, the third ground-rule is non-negotiable. You say no, it's the deal-breaker.
