Not that he's bad at laundry--he's probably better at it than I am. After all, he routinely starches and irons his shirts while I avoid the iron for anything but craft projects.
Doing someone else's laundry, especially underwear, just struck me as too personal. Still does, for that matter. *Spoiler alert*, lol, we still keep our laundry and our checkbooks separate. It works for us.
Oh, and I've only pulled the "fend for yourself" card maybe twice in the 3 years we've lived together, so I figure I'm doing pretty good. (Not counting the nights I decided to order take-out for both of us just because I didn't want to cook, of course!)
