If a guy says that you are pretty it does not mean that he likes you. He could like you, or he could just be paying you a compliment.
It means he is the problem....not you
Dude he wants to do IT!!!!!
He likes you
nothing
"Can I have you?" means, "Can I have sex with you?".
MONEY!!
He likes you
It implies that the guy thinks you are gay.
That that girl thinks that that guy is handsome.
He's lying to you.
