I can't tell if this guy likes me or not?

He's a senior, I'm a sophomore. We don't know each other too well, but he's a good guy. Friday at a party unexpectedly bear-hugged me to say "Hello". After I'd gone home, he texted me asking when I'd left, and said that I should've told him. Saturday he had me and my two best friends over to his house to hang out with him and his two friends. When I had to leave, he walked me to the door and again hugged me, and texted me saying "Come back". Sunday I'd texted him first just reminiscing over the previous day at his house. The conversation was short and I'd ended it with "Haha yeah" hoping he'd initiate the conversation. I haven't talked to him since Sunday. His texts are mostly relatively short and often seem emotionless or bland from my point of view. Is that a typical guy thing? What's his deal. I can't get a sense of whether he's into me or not.

Also, I know it might seem stupid, but I recently followed him on twitter. He accepted me, but didn't follow me back. Does that mean anything in the guy world?

There are a few signs you can look for to figure out if he likes you. If he pays attention to you, likes to be around you, is polite and respectful, seems to watch you when he thinks you are not looking, listens to what you have to say and is interested in it, tries to find reasons to talk to you and to be around you even when he doesn't need to be around you, does not expect anything from you in terms of favors, makes frequent eye contact with you, his face lights up when he sees you, puts you first all the time even ahead of himself, then most likely he likes you as more than a friend.
