look in his eyes
In truth, you can never know. You can only accept what he tells you combined with what he shows you.
if you know this for a fact, that only means one thing, he is a liar!!!
Tell her the truth.
Because most guys are telling the truth. (I am a guy)
see if the guy looks right at you if he does then he is probably telling the truth if not he is probably the guy who likes you.
He likes you. Or he is joking, but you would know the difference
the guy tells you
he would probley get upset and want to know why you are leaving him
It could be anything. There is absolutely no way to know until he tells you.
A guy is sincere if he says the truth. And if he is honest.
Either you ask him or he tells you.
Depends on the girl,if she tells the truth most the time you can believe her, but if she lies alot you can't.
