I'm sure since this thread is now 3 pages, my opinion has already been said, but....I don't think she's moved on at ALL.

That doesn't mean she's yours to pursue. I think you should call her, not see her. Her fiancee would be upset, I think, if he knew about the tearful message. More upset if subsequently she had a visit from you.

But when you talk to her, you shouldn't offer yourself up or try to tempt her away. Just make sure you're honest about your feelings even if they're conflicted, but be clear you will not cross "that" line. Wish her the best, and THEN move on.

I have to tell you, that when I got engaged about this time 20 years ago, my old boyfriends started coming OUT of the woodwork! I got a call almost every night, and NONE of them were in a position to know that I had become engaged. It was weird.

Good luck.
