I don't think anyone intentionally plays games with people, we just have two different parts of our head telling us to do two different things. One part is telling her to call you and missing you, and the other part is reminding her of why you broke up and telling her to stop contacting you for the sake of making it easier. Sometimes she will give in to the tempation of hearing your voice, so she calls you, she is probably proud and won't admit the real reason she calls you (because she misses you) and uses some lame excuse, and then to make it seem like she isn't undermining her own decision of breaking up, she will probably try and distance herself from you again. I think she still has feeling for you, but is just too confused to settle on one decision, because she doesn't know which part of her head to listen to. Their is clearly something going on with her that is causing her a lot of confusion and indecision, try and find out what it is, and if its fixable. I think deep down she does love you, but right now something is convincing her that you are not the best thing for her right now. Figure out what and maybe you have a chance at slavaging what you guys have. But with that said, don't hurt yourself in the process, if your attempts to work things out don't really go to plan, no when to give up and cut your losses, because someone who loves you won't stand being away from you for long if they no it doesn't have to be that way. Good luck.
