Look at his body language. When he's with his girlfriend and you're around, does he tend to look at you and pay less attention to his girlfriend? Does he make attempts to talk to you even though you've never talked before? This happened to me, except this guy and I talked all the time. We were at a party for graduation, and he didn't cry when his girlfriend left, but he cried when I left.
Just be yourself. (:
Ask her.
Talking to him is a good start, of course. If he doesn't act interested, then.. well, he's not interested. Guys are straightforward like that, most times.
Be extra nice to him, flirt with him. ask him about himself and try to find what you both have in common. or simply just ask if he likes you.
No, he never considers anyone a "girlfriend", he simply likes to have fun.
It means that he likes you a lot and would probably date you if he did not have a girlfriend.
Get to know her, if she seems to relate to you date her but its up to you to decide
Personally, I would be more creeped out. The new person should wait for a little bit before he tells that he likes her.
Just ask her you never no what she will say
Dakota doesn't have a girlfriend, and he never has had one.
He Never Had a Rich White Girlfriend before, He never had any white girlfriend before. Yes, he did, he wrote about her in his book, Dreams from my Father.
If you look him in the eye and smile and he smiles back then he likes you. But you might want to smile more than once so he's sure you like him and it's not just an accident or something.
