Well, it's almost a year later, and we're still friends - we keep in fairly regular contact through text/Facebook, and I went to a concert with him a few weeks ago. But things are starting to get complicated...which is saying something, considering how complicated things already felt before!
Basically, for the past few months I've been going through phases where it's felt like I have a major crush on him. When that happens, I think about him almost all the time, start to miss him a lot if I haven't heard from him recently, and also really regret turning him down before. This can last anything from a few days to a couple of weeks, but afterwards I go back to just seeing him as a friend again.

(I'm not sure if he still has feelings for me, although I think it's possible that he does, even after all this time.)
I'm getting worried - I don't want to risk ending up in a relationship I'll regret later, and I also don't want to hurt him - he's a good guy, and doesn't deserve this.

I don't know what's going on...whether it's guilt from turning him down (I certainly felt terrible about it at the time), just wanting
someone to care about me in that way (that sounds bad

), or something else entirely. Any advice would be much appreciated...
