Does He Like Me??? HELP ASAP!!?

I have a crush on this guy named Carson. When ever he sees me in the hallway he goes "SARAH!" (my name). I was walking to my 6th period and he was waiting for me right by the wall and he was like "Hey, blablabla." (Blablabla meaning I don't know what he said) and I had to tell him I had to go to cl. If I was tardy again it was detention. I was really sad. His best friend asked me who I liked and at that time I liked another guy then Carson so I said that guy. I know his best friend doesn't like me because he is madly in love with his girlfriend. Well me and Carson were on the same team thingyy it was just a 1 day thing but he asked for my #. He was like, "You gotta give me your #" then he was like "this better not be the rejection hotline =]" so we have been talking by text ever since. He ignores me when I text him but when he texts me 1st he talks on and on. He is single too. DOES HE LIKE ME?
