Why Me? why am i so dumb?

I told the cute Taiwanese guy that was in my chinese class that I liked last semester that i liked him at midnight. I'm super anxious and scared about his reply. I am a very shy and quite person in rl with ppl i don't know and boys that i like. We were playing 20 questions yesterday for a good like 6 hours cause we were also comenting on each others answers and getting topic and teasing each other. I was pretty talkitive in chinese cause one of my besties is in that class so he saw the real me, he saw me be talkitve,shy,care for the bestie in chinese when she broke down cause her pet die.d. he saw pretty much all sides of me i think. For some reason with him i was more outgoing. he was the second guy i told i liked. the first was when i was a junior in HS. he turned me down in bad english xD he was korean. the Tai guy speaks english cause he was raised in canada xD WHy did i tell him i liked him when he told me not to when we were playng 20 questions. I feel so dumb now and i can't take it back. Ugh i hate my self.
