How can I tell if this guy I like likes me back, by our chat conversations?

Ok, so this guy I REALLY like was talking to me the other day, on Facebook. He usually is kind of mean to me, but then I asked him why hes so mean to me, and he said I don't know, and i said Why don't you just get to know me? and he IMMEDIATELY said Ok, whats your favorite color?; so then we started talking for a while, and I was talking about my awesome neon tank tops I wear, and he said Oh yeah, those are sexy; so then i said thanks, and he kept saying that he really liked them, and he liked the green. And so I really want to know if he was flirting, and might like me.

ALSO: This one time during summer, I was walking my dog, and my guy friend saw me in the field by our houses, and then he called the guy I likes house, told him to come to the field because i was saying dirty things and I wanted him in bed tonight, And eventually he came out to the field, but we weren't there because my guy friend followed me home to try riding my unicycle. Keep in mind this was at 10 pm, and the guy i like actually came out to the field looking for us, and he wouldn't tell me why he came out when i asked him.

So PLEASE, do you think he likes me??
