TIFU and I need a recovery plan.

So, not today, but a few weeks ago.Backstory --> I'm in class with this guy (University), and neither of us are out, not even sure if the other guy is gay (tbh not sure wtf I am, gay, bi, straight, confused af, but whatever).So we are in class, and we are talking in a small group of people, maybe 4 or so people directly around us. We are talking and we make eye contact and THIS SHIT IS LIKE A VICE. I mean, it's the type of stare where you want to look away, but for some reason can't. Eventually, that part of our conversation ended and someone else started talking so I look away, but with this nagging idea in the back of my head ("WTF WAS THAT")... Eventually, I caught him staring at me, even made eye contact once. This wasn't like a prolonged glance, this was dead-ass staring into my soul for a solid 10-15 seconds.After class I realized there may have been more to that than I realized. I started watching him and his actions, and he tends to pretend to ignore me, unless I make direct contact and then he seems to latch on.Today after class, he followed me out of class and neglected to talk to his usual friends (which I should note are almost exclusively girls, idk if that means anything) and struck up a small conversation. I talked to him a little, but then left, and he just kinda walked away.Sooooo.... I don't want to push him away, but I'm not comfortable asking him if he likes me or whatever else I might ask. How do I get on some more solid ground?
