Search Results: how to deal with shy guys

So there is this guy that goes to a few of my classes and we are both majoring in the same program. I will be honest there was a part of me that knew he was gay based on how he talks, his mannerisms, and so on. Anyway since last semester I started to question why he acts so strange around me. He would act like he is terrified to death of me (keep in mind I am an alternative girl), sometimes he avoids me, he will feel comfortable talking with other people except me (in fact he will often grow quite with me), when I try to be friendly with him during a few exercises in my acting classes, sometimes he acts like a cat got his tongue when I try to talk to him (do keep in mind I am a shy and introverted person so even I am like wtf), one time at the end of an acting exercise I did with him, he gave me a thumbs up (I am not sure what that means but I assume that was his way of being approved of something), he said my name wrong a few times on accident, whenever we do lock eyes with each other he will look at me with relaxed eyes, he fixes his hair when he sees me from a distance, he came up and tried to strike a conversation with me once, he will say bye to me sometimes especially when it is just the two of us around and nobody else, one time his face lite up when he said bye to me, when I did acknowledge his existence and said hi to him he would give this prolonged eye contact, and in the beginning of the second semester we bumped into each other and he acted surprised saying “oh it’s you... good morning”. Those are just the few examples. Anyway, I am not sure what the reason is for his behavior around me... is he secretly attracted to me? Does he have a straight crush on me? Is he repulsed by me? Is it because he knows that I like him and trying to keep his distance? Does he want to be my friend but doesn’t know what to say to me? I don’t know what his deal is maybe I am over reading his actions when it turns out to be nothing? Someone please send help, lol.
