I would think that the logical side would worry too. Why is she still living with him? Cause it's too hard to get a place. Well, you don't think one night he or her is gonna be drunk and put the moves on the other? She's LIVING with her past 'baggage'. I say don't even THINK about it being serious until she's away from him. Cause there's way too high a risk that one or the other will try to hook up. And seeing as they're past boyfreind/girlfriend (who were OBVIOUSLY sexually active to be living together), the chances of the other saying "yes" to a "One time. For old time's sake." is very high.

DON'T GET TOO INVOLVED! STAY AWAY AND DON'T GET SERIOUS UNTIL SHE'S AWAY AND READY TO GET SERIOUS WITH YOU!
