What does a wink symbolize from your crush?

Just recently he told me had a gf since i worked my nerves in telling him my feelings. First time we ever spoken btw. He was smiling quietly, staring down and couldn't make much eye contact. Even before i approached him, he had always been staring at me on the daily basis (physically i have nice face and body) even his friends blew up his spot saying "you be checking her out all the time" anyways, just yesterday i wave hi to him and he got super happy, winked at me, and walked all masculine... Lol never saw him like that. Some people are telling me he possibly doesn't have a gf and he was just embarrass with his friend around

Would you wink at a girl if yiu had a gf and you know that girl was crushing on you?
