. . . Does he like me?

So I really like this guy. I'm not quite sure if I should like him openly, because I'm not sure if he REALLY likes me back. But he has shown some signs. Once, my strap was down without me knowing in class, and my friend alerted of me of it. He sat behind her, and when I pulled it up, he kicked my friend's chair and said "Mother *BLEEP*er." I also caught him staring at me sometimes... or should I say a lot, as well. Once, I actually looked at him in the eye and he quickly looked away. We were also on a bus, and every time I tried talking to my friend who sat across, he'd always pay attention the bus wall (He sat behind them, oddly). And later on, my friend said he kicked the bus seat (Not that hard, but hard enough to be felt). Today, his foot was twisted at an odd angle was well (I sit diagonally behind him), when it usually is straight in class. I heard that if their foot is pointing towards you, they like you. So does he like me? I want to be sure before I ask him to the dance.
