Do I actually have a crush on a gay guy?

Helloeriss01
In this class we sit in a intimate set up in class and this guy always made eye contact with me while talking so I took that as attraction lol because it was intense and he’s smiled before while looking at me. we also locked eyes once when I was standing outside class talking to the professor and he was coming out the classroom and we made eye contact.
I know I’m very pretty and I’m told often by other girls that I am but I know that I’m also smart and I don’t expect everyone to like me just because of ny looks. One class him and I were the main ones in the discussion basically talking to each other. Right after class he told the professor this is “one of his favorite classes” and made sure I could hear.
There’s this other kind of flamboyant guy in our class. He looks and acts like a gay guy and is super nice and is also outspoken so him and the guy I’m interested in have that in common. The flamboyant guy is married to a woman though and has a kid. They have other classes together and they are friends but now I’m starting to think their bond is something else.
The guy I’m interested in is dating someone and so am I but he never mentioned the girl he was dating until after I mentioned the guy I was dating.
( we exchanged a couple of words about class )
The past couple of classes him and the flamboyant guy have complimented each other. They gave each other an air high five then the guy I’m interested in complimented his shirt last class then his shoes this class which I’m trying not to think too much of. They also have each other’s number.
The guy I’m interested in usually stares at me during our class discussions while he’s talking but that’s because he sits across from me. Today someone took his seat so he sat somewhere else where I wasn’t in his eye line and barely looked at me. Only twice lol I counted.
The semester ends soon and this is extremely frustrating
just wanna know if he’s been flirting with that guy and do him and I even have a chance?
