Woman's intuition. Actually, talk to the guy or have your friend guy talk to him for you.
if your tall and the man is really attracted to you you'll know. if he recoils at the sight of a short woman you'll know.
It makes them upset because he likes her
she is simply a lesbian.(wants a girl/woman likes a girl/woman she is a lesbian)(wants a guy/boy likes a guy/boy then he is a gay)
yes.
Start talking to him and ask him what he likes in a girl/ woman. And if it starts to sound like you then you should be able to tell
when he says he likes you.
iam in love with this guy but i do not know if he likes me or some other girl
If a guy likes you but you don't know him he may look at you or walk by you whenever possible.

It means that the guy isn't gay. That he only likes woman
Not sure how you expect someone to magically know something.
