The only way your going to know if this guy likes you is ask him.
a way to know if he likes another girl is if he keeps looking at her and smiling also if he talks about her with his friends.
there is someone in the other class he doesnt want to know that he kinda likes her
Well if you do not fancy them but they fancy you, you should say "I want to be your friend but I am not ready to go out with someone at the moment". and if you do fancy them, try and get to know them, then see what happens!!:D
No it means he's nosy and wants to know who it is!
I would say if you think she likes you, take a chance... chances are that she is too shy to make the first move (i know i am) so just go for it!=)
Just be near him read his face and eventually you will know
Let him know you fancy him, that always gets a guys attention, he will probably start to like the idea of you and start flirting. if he doesnt, then he just isn't attracted to you. Find out what he likes and start to do what he likes he will soon like you
When he has a penis.
You know if he likes you because he would give you hints that he likes you in the hallway or after/before school, or he would ask you out.
Soo...how to know if someone likes you, if you know she likes you?
Just all of the normal signs that someone likes you!
Easy, ask one of your friends or a friend of his that you know to casually ask him. If he doesn't like you then I'm sure you can find someone better.
