So about a year ago I met this girl at a party off campus, we hit it off pretty well that night and I figured I would see her around campus later so I didn't bother for her number (plus im a big pussy). After leaving she somehow got my number and we start spending time together on campus (lives in the same complex as me). We starting spending more time together but I never really took her on a "date". I liked her but I'm pretty picky when it comes to women so I just thought it would be fun to have a girl around to hang with the guys so I friendzoned her (the most we ever did was cuddle) and brought her into my circle of friends. Fast forward to about a month ago. She starts going out with one of my friends (roommate for three years in school who is now graduated and works in the area). I can see she still really likes me as more than a friend and might be doing this to make me jealous. A few weeks ago she breaks up with him (happens alot to him, he is way too nice) but he still really kind of hangs on her and she still wants to be friends. He is always texting her telling her to come hang out but she blows him off because she's always hanging out with my friends and I. Last night my friends and I (her included) go out the bar we get pretty drunk, go back to campus, and end up having sex. I don't have the heart to tell him that she blew him off for me. I told her I didn't want a relationship at all but I enjoy her company and we will probably just end up fuck buddies. She was fine with that because we have totally different career paths and we are graduating soon. What should I do OT? Should the I tell him what happened? I was hanging out with him today and I felt really guilty. She is still kinda leading him along because they are going to some formal dance in a few weeks. He thinks they are going to get back together while she is really just doing him a favor.
