<human>: I've been rooming with this guy for a little more than a year.  He's definitely one of the chillest guys I've ever met.  He's really smart, sweet, and funny.  I really hate it when he brings random girls home to fuck but I can't ask him to stop without revealing how I feel about him.  Does anyone know of a way I can show him I care about him in a romantic way without risking our current relationship?  He already asked me if it was ok if he brought girls back to our place and I said yes (stupidly).  I'm afraid if he'll try to find a new place if he has to change his lifestyle but I really enjoy living with him.

Could you distill the essence of the text into 1-3 sentences?
<bot>: In love with a roommate that likes to party and brings home random girls a lot.  It really bothers me but I don't want to ask him to stop without ruining our potential relationship.
