Help! I have a problem!!!?

Alright, I've liked a guy for a while, and I'm trying to determine whether or not he likes me back. He has: Called me cute over text, played with my hair, stayed the night at my house with his brother and my BFF, wears cologne (his brother doesn't), always tells me we should hang out more, flexed his abs, pulls me around my pool, laughs at all my jokes, always seems to be next to me whenever we're hanging out in a group (always), he usually borrows a pair of my fuzzy socks when he's over, he randomly jumps into pictures that are intended to be just of me, and one night he calle me princess for a looong time but not like he meant that I was being a princess but that he treating me like a princess. He seems to flirt with me too, and my BFF thinks he likes me, but he's 'married' on facebook and has tons of girl (space) friends who he kinda flirts with on facebook. Help!!! Does he like me!??! Sorry my spelling, grammer, and puncuation are all sooo bad I'm usually better but right now I'm losin it wondering if he likes mee!!
