Girls:Ever avoided someone because you had a crush on him?

I always try to avoid my crush whenever I see him. But i only avoid him in real life. I never avoid him on Facebook because on real life, i don't want him to see how i get nervous and how i blush and freeze. but on Facebook, he can't see me so i think it's better when i'm talking to him in the computer ^^ and u already have my e-mail.
