I told my crush I like him and now he won't talk to me?i don't know what to think?

i told my crush I like him, like two months ago. and he told me that distance is a problem. I think he likes someone. he lives in utah and I live in san diego. but he keeps visiting and I don't know why...he visited on Oct 16. He winked at me the night we when bowling here in SD and when he was back in utah he talked to me over Facebook and said "Don't take this the wrong way , but you looked really good" what am I supposed to think? then I said "thanks" now he won't talk to me.. why? I've had a crush on him for most that a year..help!? should I start a conversation over Facebook? does he like me?
