I think my classmate has a crush on me or something?

I just started summer school in my college. In class, as soon as I sat on my seat the first day he smiled at me and said Hi. Then we made small talk. Then later when the professor was lecturing, he asked me silently to add him on Facebook, so I did. As soon as I approved him, he looked at my profile observantly, when I looked at him he immediately switched to another tab. Then he started updating his Facebook saying his partner in the group sucked (he posted that two seperate times), and he asked to "pleaseeeee work with him next time as his partner." On the first day when class was dismissed, he tried to wait for me, then I said bye to him because I had to ask the professor a question. He winked at me and waved bye. Also, during class he told me I can come to his workplace any time and he'll be there. In his pictures on Facebook, he seems to have a bunch of friends. I'm kind of flattered that he may like me, but I don't like him like that ahaha. In his profile, it says he is interested in "women." I'm bi and it says so on my facebook. Do you guys think this guy is superrrr friendly or likes me? :)
