Ahhhhhhh well I don't have good advice here I guess. But I can relate, having been there. Of course my XW was saying things like "I wish there was some way we could work this out," so I was trying to gague if there was something more to say. But there in the end there wasn't much stopping me from saying something like "Are you absoltely sure this is what you want, we can still walk away" - if you're worried about that her solidifying her point of view, there's really not much more solid than that signature. And honestly I was in a "nothing left to lose" mode too, I guess.
I don't think there is any loss of dignity in acknowledging the significance of the moment, and speaking up for your marriage.
Hang in there man, I know what it's like. Good thoughts your way.
