Tough problem. However, I think you need to talk to this guy and tell him how you really feel. If you are this close to him then talking should be easy and he may feel the same way. Maybe a solution can be worked out between the two of you.
I agree with Emmyful. You need to let him know that you still like him and it appears as if he still likes you too. He probably really likes this other girl too and is stuck. Don’t jump to conclusions though, and don’t shut him out completely. Trust me, that could be a very big regret.
How can I put this politely…. I would encourage you to read the FAQ about Ficlets which talks about what this site is geared for. It isn’t intended to be a place to blog, or to push a writer’s real ficlet off the ‘Recent Ficlets’ list in order to ask for love advice. This isn’t the place for that stuff. Try writing a story about your angst. You wouldn’t draw the ire of cranky ppl like me if you went about it that way ;)
