You talk to her and ask her what is wrong ,or what she dose not like about you.
Talk to him about it
Possibly, the only way to find out is to talk to her.
It depends! If this boy often smiles at you, looks at you or trys to talk to you then yes otherwise he might just have smiled because he thought you were smiling at him and it's the polite thing to do
She could just be a very good friend. But in most cases, this is true, she does like you. :)
that dose not means he like you it just means he like to firt with you i know you should talk to him hang out with him sometimes
He probably doesn't like you or hes just too astonished to talk.
Ok look if u really like him u should ask him out
Talk to her more.
Yes
Well if she never smiles at you or if you try to talk to her and she totally blows you off, chances are that she isn't that fond of you.
Well talk to your friend's gf see if she realy dose like you. if she dose get your friend to trust you and talk to him.
