Being friendly doesn't mean that she likes them as well. You will know the girl likes you if you ask her for a date then she agrees.
Then when she ask you to come in to her place and asked you to have a drink coffee or beer whatever is it.
It means you have to get ready for the next scene boy..............
a shy girl she is
Maybe he likes her.
Ask her.
He likes a girl with nice eyes, especially blue.
Depending how she looks at you. And if she looks at you dreamly then she likes you.
Not every boy that says hello to a girl likes the girl. He may say hello to be friendly.
Just be a friendly person and watch things she does or likes to do so you could start a conversation
Just ask him if he likes you or the other girl better. Just don't do anything you might regret if you get an answer you weren't expecting.

Be pleasant and friendly to her, and try not to act like a jerk around the other guy. And give it time. Most likely that relationship will not last forever.
