DAMMIT I mess everything up!!?

anyways there's this very friendly/talkative/social guy in my extra curricular art cl which now ended for the summer. I added him on fb and he posted a pic of the art he was working on for a year cuz he was done. I commentd then he was like yea took me long enough eh? and then I said :) eh but it was worth it- what was your inspiration and he idn't reply for like over a day and he was on fb and had a convo w/ someone else on his wall. I guess i came on too strongly cuz we havent really talked that much. what do i do now? i feel offended and i really like him now he think im like creepy/clingy and he doesnt wanna talk to me
