Problem

So, some interesting developments in my life. I just found out that one of my friends' ex-boyfriends likes me. I don't know what to do, because he is a really great guy, but I see him as a friend (and I told him that too), but he asked me if I find him attractive, which I do, but it doesn't mean I really like him, you know? Attraction can not be the only thing. I think I would rather just stay friends with him right now. Plus I have a guy right now, no matter how annoying he is at times, wanting something I don't want to give up and such. I don't think I would leave Alex if David (the friend's ex) asked me out. I don't know. He's is just such a great friend and I think under the circumstances I don't like him, but I think if I wasn't dating someone else right now I would date him, I think. The friend ex thing doesn't really bother me because she broke up with him, so it changes the rules of engagement in terms of dating an ex. Right now, we will remain friends, party buddies, hanger outers, like Sean and I are, and Mardig and I (really really really amazing guy friends).
