Depends on the guy. It could either mean she doesn't feel comfortable around him. I.E. finds him repulsive/shy etc. Or it could mean that she likes him and doesn't know what to say.
If it's you I'd say go for it. Initiate it. If she doesn't respond. Then you win some you lose some. Life goes on
it just means that the girl is embarrassed to talk to you around her friends so she really isn't a real friend
She may mean that she is embarrassed to be liking the boy if he's not well liked in her circle of friends, or in general. The only way to clarify exactly what she meant is to ask her.
When a girl smiles at a guy and then looks down it usually means she likes the guy or thinks he is cute, but is shy and maybe embarrassed. She may have a crush on the guy and want to go out with him, but feels shy and embarrassed when around him.
When a guy gets embarrassed around a girl, it can mean many things. If you mean shy then that's a different story. But being embarrassed means feeling ashamed. He might think he is too good for this girl and everytime she gets around him he feels ashamed and doesn't want to be seen with her.
Most likely, yes. Unless she has a speech impediment, then it means shes nervous around you and doesn't want to be embarrassed when shes with you.
It means he/she is embarrassed around you for some reason.
Either she likes you or she is embarrassed.
He's excited like happy!
it could mean that she is shy or that she likes you.
a girl who gets what she wants...and is a pretty girl
it means she really likes you! she likes when she gets to see you or be around you.
She is probably self conscious at least to some degree, even though she might not think so. She might just not get embarrassed very easily. She could be very outgoing or just not care what people think about her.
