It may mean that the guy is starting to like you and wants to know you more and that's why he is talking to you more than usual.
If a very outgoing guy goes quiet near you and listens to what you say he'll most likely have a crush on you.
He may like her.
it means he likes you
An outgoing guy might like a girl who is outgoing as well. He may like a girl with a sense of humor, who likes to try new things, and is fun to be around.
It means that he is shy towards you. That could mean that he likes you, or he is uncomfortable around you.
Yes,because he knows that he has to act like himself around the one he likes.
The only way to know is to ask him and see, though honestly if an "outgoing guy" is "uncomfortable" around you, it's at least a reasonable bet that he doesn't actually like you all that much.... outgoing people don't usually get uncomfortable around people they like.
If a guy is loud around you, it could mean that he is trying to get your attention or show off in some way. He might be trying to seem confident or outgoing in your presence. Alternatively, he may just have a naturally loud personality.
That means either he's not really into you or he really likes you and i very shy about being around you.
That is possible but sometimes that may just mean he is embarresed to be around you.
It means he likes you. but has no idea if you feel the same way or not. if you are interested in him, tell him
