Hi South-east boy.
My advice to you would be not to contact her again. It would only upset you more and delay the process of your getting over her. Maybe you could force her to admit that she lied to you or treated you badly, but I don't think that there is any way that you will get her to change her mind about her relationship with you. So, I don't think you have anything to gain by it. Of course I realise that someone's advice has very little power when compared to romantic feelings, so I quite expect you talk to her again.
Another point against keeping in contact is that if you do, at some point she will probably refuse to talk to you again (but for good this time), and that will just cause you more pain.
She may have great outer beauty. I don't know. But inwardly, she is not beautiful, whatever she thinks. I think you are lucky that you didn't go out. As you imply, it might have been you that married her then, and I think in the long term, her true nature would have made you unhappy.
It is strange that this kind of thing happens repeatedly to you. As everyone else has said, you seem like a nice guy, and you deserve much better. Is it possible that it isn't just a coincidence somehow? Is there some behaviour of yours that might have led to it. Maybe embarking on long distance relationships without a definite timescale to be able to live near each other?
I've learned from bitter experience that when you are dumped, it seems very important to find out the reason from the dumper, but that there is nothing that they can say that will help you. The best policy is cut off all contact with them, at least until you are over them emotionally, and if they have treated you badly (as she has), then forever. I know that there is a 95% chance that you won't follow this advice, but I think it is good, so I have to give it.
It is true that at some point she might come back to you if it doesn't work out with her current victim. You need to work on being enough over her that you can tell her where to go. I agree with what Jam said
'NO! i would be if i take her back...'. I can't cut and paste smilies, but they were spot on.
