The fitting in with the controlling rules of a female room-mate, I do not.
If you share with someone, then of course you have to respect their wishes and have shared house rules, but room-mates do not decide who you date and when.
Maybe he doesn't want to date her ~ or maybe there is something there ~ who knows.
Anyway, that doesn't mean she doesn't want to date him.
Trust me she doesnt' want to date him. She's married to someone else right now who lives out of the country at the moment & is in the process of moving here. He does care about her, but only as a friend.
