I don't understand? What happened?

Yeah she probably liked you initially but now she's lost interest. Guys saying things like "how come you won't talk to me" signals weakness and neediness, which is a turn-off.

def. stop asking her stuff like why won't you talk to me. Chances are she liked you, but not in the same way you liked her - then when you started taking too much interest and or contacting her too regularly - she backed off to signal her lack of interest. If you are looking for more than a friendship - everything she is doing right now signals she isn't available for whatever reason. You need to take her signal seriously or risk losing her friendship. The best way to start a real relationship is a friendship - so back off unless she contacts you - right now you are too available & seem too needy - which isn't attractive.

I know this question is for the girls but how long has she been out of touch?. We tend to get too hung up on technology and it could be something simple like her phone got wet or dropped or she went way over on minutes. Some people rarely check email. She could be out of town - or if she's under 18 maybe grounded? Don't always assume the worst.
