Man, I too am sincerely sorry to hear what you're going through.
Forgive me for not saying much, but Mr 5 0 pretty much said everything that I would've said (and quite articulately, too). I would definitely pay close attention to what he said. BTW, I also agree with what jocatmust stated about living together. I am sure you gave her the wrong idea, even if you guys discussed "putting it off for later". In her mind, she's kinda perhap's been expecting more and it may have seemed like with you, she may have just been doomed for forever girlfriend and boyfriend.

Moreover, I don't really know the girl or your relationship with her, but from what you wrote, it seems like this is temporary. When all is said and done, there's been much more of a foundation/history set between you and her and he is just a deep pothole in the road. He cannot beat what you 2 had. I don't want to give you overconfidence in the situation, but that is what I feel. I know you aren't gonna automatically feel 100% better from what anybody here has written, it's just gonna take time, hopefully not much time as she will see what she is missing and come running back. But it just depends on what you want. How serious are you about her? Doesn't mean that you have to run back to her and say that "I'll marry you if you leave him for me." Just saying that she may be more serious about it then you may be and since you're not, she is looking for someone who is.

I hope I haven't brought you down with any of what I wrote, just trying to lend a hand and I hope whatever happens, that it works out for you. Don't forget, you are still young, free, and living in America.
