Shy girls, what do you say about this ? why should he still be keeping away from you if he liked you back ?

Because he got humiliated. He's hardly going to try and talk to you now that your friend embarrassed him in front of you. Maybe you should try talking to him, tell him you're sorry for what happened and your friend was just trying to protect you or something. He tried to talk to you and was brutally rejected, so now it's your turn to make that ok. Good luck!
