I did tell him how his attitude makes me feel disrespected and like he expects me to be his maid/surrogate mum... He brushed it off every time. He really doesn't think it's a big deal and he doesn't mind the mess himself. More even, sometimes when I tell him to pick up his leftovers he gives me the "You don't always pick up your mess, either!" spiel and suddenly we're discussing my lack of housekeeping skills... and I'm just sitting there thinking, how the heck did we get to that?!
