Most the time these are signs of flirting. He might like you. The best way to find out is ask him. If you like him, let him know how you feel.
1. If he stares at you 2. if he talks to his friends about you 3. sometimes avoids you on purpose , but not in a mean way but in a shy manor
he might like you or hes talking about you
if his stare show caring or love, or something like that then yes
From personal experience yes they like you
It means that you have something is on your face
If he "sometimes" looks at you, or stares at you "without expression" it means one of two things: You are obsessed with him, or you are very, very paranoid.
He wants that girl.
It doesn't "mean" anything, it's just how he acts. If you want to know how he feels ask him, don't ask us ten thousand variations on the same question.
YEAH! go girl when a boy is mean to you and then nice he totally likes you
He loves you
Well maybe It depends on how much he likes her probably sometimes!
It means she is teasing you.
