Is this classmate into me or am I overthinking the eye contact?

There's this guy in my class who I've never talked to before. He's a year older and we don't have many mutual so I haven't had much of a chance. He plays hockey with my ex, so I know he knows me. The problem with that is my ex told me that I was pretty popular amongst the hockey guys and a lot of them thought I was good looking. I asked who specifically said that, then he switched and said they were calling me ugly and teasing him for dating me. My ex is a major ass hole, so I don't know if he was lying. Either way, the first name he said was the guy in my class. This was a while ago, but thought some background info may be beneficial. Anyway, we sit next to each other in class (assigned seating) and his friend sits behind him. A few weeks ago, I must've zoned out looking at him, because I snapped out of it and we were making eye contact. Since then, I feel like he's been looking at me and trying to catch my eye, but maybe I'm just more aware of him? He also sits facing me rather than the front, but that may be so he can talk to his friend behind him. I have noticed he fixes his hair a lot and looks in my direction while I'm with friends, but I can't tell if he's looking at me or someone else. I don't have him on anything social media because he only has friends/people he knows personally. I think I tried to follow him a year or two back, and he didn't follow me, so I'm hesitant to try again. I don't know if I should feed into the eye contact or follow him or just wait and see if he makes a move. I'm very awkward and would prefer not to have to sit next to him for the rest of the year knowing I made a fool out of myself. Sorry for the essay. Opinions would be GREATLY appreciated.
