What's wrong with her?

My girlfriend has been acting wierd for about a month now. The thing is that she doesnt speak to me much. Like 1 SMS per two weeks and they are in the fashion of 'Please leave me alone, I want to be alone.' She wont answer her cell when I call her, she wont see me if I go to her house, she wont communicate with me in anyway, and still she says she wants to continue our relationship... What the f*ck would you have me do?

First calm down. Then maybe ask one of her close friends?

Have you done anything bad that she might have found out about? Maybe she's done something she regrets and is trying to get herself together? Or maybe she just needs a break- some time to be alone. Or perhaps it doesn't have much to do with what you've done- but with her parents not approving? Or something important going on at home.

Try sending her flowers with a cute message. Then call/text/email her to see if she got them...

try asking her what's wrong, and if she says: 'nothing I'm fine thanks for asking'
you get mad and say: 'no you're not fine, it's been a month now, and I can't keep this relationship for too long if you don't stop acting like that, COME ON, talk to me I'm not a total stranger!!!'

thank god I'm not a boy,
cause if I were you, I would break up with her, or break her head off!
I'm not telling you to do that, but you need to show her that you FEEL that there's something wrong with her, show her that you care about her while she's NOT!
tell her that you can help her, ask her to trust you (be sweet when you say that) lol

goood luck!!
