What should I do? I'm infatuated with a married man who is a teacher?

I am in college and I have a teacher that I have an extreme crush over. I'm 21 years old and am mature enough to know not to do anything about it because I know it's mainly infatuation and I guess I have a thing for older men(he's 33). He is happily married and extremely professional, it's weird because sometimes I can't even keep eye contact with him because I feel like he can see right through me and also he reads body language like no other person I know. He has told me I was really pretty and I literally stopped breathing but pretended like I didn't even hear him and when I think about it Now I wish I would have at least thanked him for the compliment! Anyway my question is how do I get over this feeling? : / I am not a home wrecker and would never ever flirt with a married man and he would never flirt with me but I feel like its affecting the way I act around him. Should I just drop the cl? It's little frusturating. Thanks.
