Shyness...fwb to relationship?

This might be interesting to read. Treat it as if the target is a girl with a male mind I guess...

I know this guy who just came to school as an exchange student (Brazil). He dresses kinda conservative (I would say "normal" and not effeminate but still has some clean-but style without the preppiness; he's cute and looks a little young for his age. He's shy and anxious, but I'm sure he knows he's attractive. He's also kind of "the new gay guy" at our small college, so the others talk about how good-looking he is. He was with two guys before but they are toxic people who basically tricked him into liking them and hurt him. He still texts them though, for some reason or other. Especially when he gets drunk.

Now we have hooked up twice, but didn't have sex. I have no idea whether he wants a relationship, friends with benefits, or nothing anymore though.

He is very busy all the time and is very committed to studying, while I come off as much more social. He's always at the academic commons, which is a place to study but also talk. He tends to avoid me whenever he's doing work though, but will say hi if we pass each other. I don't know whether he's too shy, as he has told me he gets very anxious and shy until he's comfortable with people (and I noticed that while hooking up, although when drunk he is much less inhibited), or he just looks at me as someone to hookup with on weekends (which I don't like), even though we haven't had sex on either occasion. He has told me he doesn't like feeling like a piece of meat before yet his words kinda contradict the way he comes off at times. Imagine shy in public but the opposite in person; it throws me off a lot, so I'm wondering if he sees me as another option, wants me to make the moves, or is just too busy. He told me he's not good at making friends, especially males ones (same here). He has mostly female friends.

He told me he has dated older guys but broke up with one because the guy was getting too clingy. The weird thing is that after we kissed at a party, he was holding my hand and has been so affectionate while in bed, but he doesn't initiate any conversation anymore. I'm thinking maybe because we didn't have sex and he expected it. Then the next day told me he hadn't been giving me attention because he was busy, which confused me as well. He doesn't text me at all anymore but will respond to texts, yet he seems to kind of cut me off (by not continuing the conversations), maybe due to being busy. He used to like a lot of my things on facebook, but stopped. That also threw me off, so I deactivated it (for different reasons). I ate with him yesterday though, and he noticed I deactivated it even though I had only done it like an hour before that...

What can I do regarding this? I kind of want something to increase his attachment to me, and I know having sex with him might help. I just don't want to get attached myself, especially if he doesn't want a relationship. He also told me he's here for only a year, which I'm thinking might be his way of saying he doesn't want a relationship for fear of having to end it relatively soon.

Just cut out all this discommunication nonsense ("likes" on FB and whatnot) and talk to the guy.
