Excuse me for stating the absolute obvious here lol. If you're living together, chances are that if something's gonna happen, it's gonna happen! Just please, please make sure it's not when you're both drunk or out of your faces on whatever (not assuming anything. Just a hypothetical situation), because that's the tempting thing. Make sure that you and he are completely sober, because if not, one or both of you is bound to regret it.
I really hope this doesn't sound preachy. It's just that I was in your situation several times - I have a habit of falling in love with my male friends, it's actually quite laughable - and each time I ended up losing a fantastic person because of what happened under false circumstances.
So just hang in there even though it hurts, and in time he may very well see what a catch you are, and you will be that girl. Patience is a virtue, if a frustrating one.
