The day I was supposed to leave for the summer to start a fellowship, we had class together. We had been talking to each other more since we were working together in the class (he asked to work with me, in case it matters). He knew I was leaving that day, and after the class ended walked right past me without saying a word and left. I basically didn't hear from him all summer, save one time when he IMed me to ask how things were going.
When I visited at the end of the summer, all my labmates were there and we had a good time chatting and catching up, and the whole time I was talking to everyone else he just sat on the couch staring at his laptop with a grumpy face. I didn't say anything to him since I had spent the summer trying to forget about him and didn't want to deal with him anymore, and he didn't say a word to me.
I thought I would be over him by now, but now that I have to see him again my old feelings are coming back, and it hurts because I just dont' know how to forget about him. I have no idea if he ever had feelings for me, but I think it was all in my head because there's another girl that he's started spending a lot of time talking to, and he's always smiling and laughing with her, but with me he always used to be withdrawn and nervous and we could barely talk to each other, even though he was always hanging around. Now we pretty much just ignore each other, and the only interaction we have is sometimes I catch him staring at me and he always looks away really fast, but we haven't even had a conversation since I got back. I guess I'm just hanging onto a fantasy that he has feelings for me, when in reality he never felt anythign for me and is now interested in this new girl. I think the only way I can get over him is if he tells me he doesn't care about me, but I'm too afraid to tell him how I feel because I'll just end up humiliated and make things really awkward. So how can I forget about this guy and finally move on?
