You will know if he's really interested in you cause he will talk to you a lot, he will look at you a lot, also he'll component you a lot!! :)
Tell him he's disgusting and your not interested.
Kick his butt and force him to tell the truth
when he doesnt call u back or gives u odd glares...good luck!
bang him. if he says he liked it then hes into you
If they are really interested in you they will tell you or leave enough clues that you know for certain.
You can tell by if they don't send a message back in the next 20 seconds hes probably thinking what to say buy if he doesn't send a message back in the next 40 secs he not interested.
tell one of your friend to go tell him you like him and act that you did not know and then go red
It depends What Hes Interested In....
Hes obviously not interested in YOU. All hes interested in is your vagina.

tell him if he laughfs hes not worth it
Nobody really knows but i can tell you now ... hes a p***
