She won't talk to me

She is probably just really shy and it will take her time to get to warm up to you

I'm the same when I talk to my boyfriend because I don't know what to say and I'm afraid I'm going to say something that's going to make him not like me or something.

Can you please give more details? I'm a good advisor but I need more details about this problem.

No one can answer that without more info. If you're really worried, go to her house or call and ask her parents if she's okay.

Ha! I'm having the same problem. Not my girlfriend but someone who I thought was one of my best friends. We used to talk every day... so I'll let you know how my situation works out and take what you can from it.
