When is over really over?

Have you ever been a relationship only to have that relationship called off for some reason or another, just to have the person you are cooling off from, contact you? Break ups to make ups they say; but my question is when does it really count? When does a female say i'm done and it really means it? Of all the women I have been involved with, the ones that have for lack of a better term dumped me always contact me within a reasonably quick time period to "talk' or to say they miss me or they made a mistake. How am i to know when she says she's through and she's really through? May seem like a dumb question with the obvious answer being you know shes done when she doesn't call your ass back! But they have always called back. and why is this a dilemma? Because i move on to the next one pretty quickly. So if you say we're through on Tuesday saturday i'm watching Loves Jones with my new boo (too far?). OK maybe not that exactly but you get my point. And it's a sticky situation because I may want to rekindle something with the girl that dumped me but im far too stubborn...so instead of looking for ways to get back with the ex i look for replace to move on with the next. However if i knew a girl said its over but didnt really mean it i would be more than willing to try to win her back. I just feel bad when a girl comes back into my life and im emotionally no longer attached to her. So ladies let me know (1) why do ya'll do this (say you're done when you're clearly not) and (2) how am i to know if you're done or just need a breather.

Simplicity:

1. Sometimes the things women do are unexplainable to anyone except to themselves. There's something empowering about letting go of something you may love terribly but may not be necessarily good for them. Kind of like drugs.... imagine an addict finally able to quit and be clean... its encouraging as hell to be able to give up something. Not to say men are a woman's drug but in a sense loving certain men can be and before the addiction gets to the point of no return its important to her to know she is able to come off that high without the constant need for it.
2. The only way you can truly know the answer to that is if you can see the future! no i'm just kidding. but 9 times outta 10, if she's calling you despite her decision to not speak anymore, and if when you speak to her or even just think about her you can't help but smile and your heart still skips beats from the sound of her voice... it's not a matter of her truly being done it's just a matter of her trying to gauge how strong your love it and being hopeful for something better to come because she probably has just cause for ending it... ultimately yes, when she's done with you she'll stop calling but you also have to think about why she may stop calling other than that because it may be something you need to do and only you can do it to change things.

I speak mostly for myself and the logic of women who can't put words to it.... but i don't know if these responses hold true to everyone, but they most certainly do to me... does this clear things up for you Sean? Or does someone else wanna take a stab at it?
