She want to break up our realetion.

Don't worried...still many pretty girl in out there... lost one... you will get more later... keep smiling and focus with your work and your life...!

You know what, if your girlfriend wants to break up with you then, let her go. You already know the fact that she doesn't love you anymore. So if you really love that girl, you should release her. Let her find her true happiness. Maybe she's not really for you. Just give her the freedom she wants in order for the both of you to have peace of mind.

i think it's better to move on. =)

Well you said you two had an argument few days ago. So, maybe she is still said and sulking. I guess give her sometimes to cool down, maybe another few days. No need to take rush decision. But if she continues ignoring you then you better just break up with her because no point being in a relationship but don't want to talk, that is just not making sense. Whatever argument happened, you two can always talk about it and apologize to each other. Ignoring, not talking, not answering, and playing a puzzle is not a right way to handle relationship problem.

give her time to think and space to breathe... maybe when the right time comes she will talk to you. You can still continue to send her messages telling her you still care (if you still do) tell her how you really feel and how you're wanting to talk to her when she's ready to talk to you. Otherwise, you can just let go and get over it.
