Do you think he likes me?

So this guy in one of my classes is my partner for partner activities and we've become friends. He's really nice and funny and we laugh and joke. One day he came up under my mutual friends on facebook and I friended him. He accepted, and liked one of my pictures which means he was looking at my profile. The next day in class when we had to play a memory game with our partner, he said "you friended me on facebook last night" and i said "yea". Is it a big deal? And during the game we were laughing and joking around, I guess flirting. And last night at homecoming i saw him with his sister and a girl friend (not his gf cus he's single and they didnt kiss or anything like that). The whole time I saw him looking at me dancing with my friends. Do you think he likes me?
