I'll be straightforward:

I think it's time to cut your losses, because I don't see how this can possibly end well. The reward no longer exceeds the risk, at least from my outsider's point of view, and this whole endeavor appears to be sinking further into the red. You're putting more and more effort into it (possibly to the detriment of your health), and you're getting less and less in return. I mean, you said in a previous post that she officially dumped you. After that point, anything she does to lead you on, intentionally or not, is just yanking your chain...so to speak.

Bow out gracefully. Tell her that all of the uncertainty is driving you crazy, so you've decided to back off. If, at some point in the future, she gets her (stuff) together, she can look you up. Finding Peter and telling him all that has happened in order to drive a wedge between them is a bad idea. She would see that as selfish and immature, and she would be correct. If they were to break up because of that, it would not be to you that she would turn for comfort. You would be at the bottom of her list, not at the top. On the other hand, a confrontation like that might make for a good story someday, but it's basically your "nuclear option," so...nah, just don't.

Again, this is just one American's view (which will probably serve to reinforce someone's stereotype of Americans somehow). I'm about as removed from this as it is possible to be, and my perspective on it may not be reliable. Do what you think is best.
