Did my crush actually ignore me?

Helloeriss01
I’ve never had the problem in college of not having a guy interested if I wanted him to be or looking at me it’s just getting him to make the move.
We have a very small college class and we all sit in an oval where we can see each other. He caught my eye quickly because he’s very quirky and he’s the main one to speak up in class always.
He is political and I’m not but he’ll always speak on a political issue or something and he is intellectual.
He usually sits across from me or diagonal. Somewhere where we can easily make eye contact.
Literally everytime he opens his mouth to speak his eyes will eventually meet mine and he’ll keep glancing over at me while talking and at first it was uncomfortable because I think other people notice.
He’ll try to break eye contact with me and then scan the room or another person in his eye line while talking but he usually looks at me the most.
There’s this married guy in our class who he’s super close to and has his number and always talks to.
Once the guy did try and talk to me before class about how it was nice to be watching a movie but I said I was gonna go call this guy. So he knows or thinks there’s a guy in the picture with me and only after I mentioned that did he mention his random long distance girlfriend in class who he’s never mentioned before or since then.
He even said long distance was a problem.
Also one class I talked out a lot and him and I basically had a discussion and after class he told the professor it was one of his favorite classes and I heard him.
Once he was having a joking debate and I kept looking at him and smiling and he was smiling too and kept looking back at the person he was talking to then me.
Today I was walking to class and i saw him come out the classroom. I looked up from my phone and he was slightly smiling and looking at me so I said hi to him and looked away but I don’t think he said anything back because I didn’t hear lol. Maybe he did. Why would he ignore me?
