Is it weird that i'd like to stay friends with my boyfriend's friend?

A friend of mine/my boyfriend's long-time friend dropped a huge bomb on me about this time last year. He admitted to having feelings for me. It created a lot of issues, and we pretty much quit talking until recently. The last two times I've seen this guy, he's had to ask if I was still creeped out by him (he asked me again when we hung out last week. He also made it a point to ask when we were alone for a brief period of time). Before the night was over, I went outside, and he followed me out. Granted, he talked to me about his new girlfriend, but I still got the impression that he just wanted to take that moment to be outside with me alone. I told him I was happy for him.. He seemed to be slightly taken back by this at first. He also seemed to be generally about the fact that we are apparently on friendly/speaking terms again.

I met his girlfriend yesterday. She seemed sweet and quiet, but my boyfriend/friends commented that she's not the type he typically goes for (physically). I have my doubts that his feelings for her are genuine. In fact, I'm kind of starting to wonder if maybe he's trying to get under my skin with this. The situation as a whole makes me nervous, but maybe I'm reading into it too much.

Is it likely that he still has a thing for me..? Is it ridiculous that I'd like to continue the friendship, if at all possible?
