How to get over a crush that your 99% sure isn’t interested in you and you never talk to?

Title basically says it all. I met this guy in my calculus course and we make eye contract a lot, I’m sure I look like a dumbass since I freeze up every time we do. We don’t talk, I don’t think he likes me back but I’m still stuck on him for some reason (it’s been like 2 months)
