He's testing your weaknesses and power-points
it means that he thinks your funny and cute
Sounds to me that he's really into you.
He's interested in you.
He likes you, ask him out or he won't stop! Trust me on this one!
it means she / he likes you
You can know if he stares at your face and stares into your eyes when you two talk. If he stares at "other" parts of your body get away from him because he is a creeper and a pervert. You should then think if you really like him as more than a friend, if you do then tell him, if you don't then don't let himself make a fool of himself and just tell him (as gently as you can).
no, it doesn't mean he does because I've learned from personal experience that a boy is very good at sending mixed messages
He likes you.
Yes He Does Likes You
it means she either likes you or or thinks your eyes are pretty
if his stare show caring or love, or something like that then yes
No, he is undressing you with his eyes.
its shiny
