Last year I took a class and had a huge crush on my instructor. I told him and he wanted to keep the relationship professional since then I keep my distance, and I don't talk to him on face book. At first I thought he didn't want anything to do with me anymore until I marked I was in a relationship, then I was ale to see his wall, which I still don't understand why. I would like to talk to him again but I'm afraid he might think I still like him, it was only a crush, I didn't want a relationship. My question is why can't I stop thinking about why he treats or acts around me? And why couldn't he just tell me he didn't like me?
