could be a number of things:
you got on bad terms with em
to assert dominance(who knows why)
possibly a way of flirting
It could mean that he doesn't like you or he just thinks your annoying and weird in general. I've had a guy look at me that way and i just ignore him.
I am a guy so I would know. First of all I have been disgust by a lot of girls so if he looks at you in a wierd way or just makes an escuse or something like that you would know.
It may very well mean that a drugged guy is looking at you
That he wants to "get to know you better."
They have the same interests
he is starstruck
Nothing. He is a nice guy.
it means she likes him
Not necessarily.
He's admiring from afar...
He is simply a guy! guys do that unfortunately!!
if a guy looks at you with his eyes popped out it means he likes you!
It depends what her stare looks like. If she looks at you in disgust, that means she finds you gross or yucky. If she looks at you in awe, that means she likes you or finds you cute, hot or sexy.
