Thats all you can do strange...let her take the reins on that, but don't fight her. That is the worst thing to do.
My W has brought up D too, but just seems to keep putting it on the backburner...now, when she finally broke down to me after a R talk, she said it was demons from her past muddling her decisions of reconcilation. But at least she hasnt followed through with D yet.
Point is Strange, dont believe a word of what comes out of a WAWs mouth until you physically see D papers in front of you, and even then accept it as though it doesnt faze you that much,(even though it might tear you up inside). When I finally got to the point of wanting and not needing, I feel D papers wouldnt bother me as much as if it were to happen 8 months ago.
Just follow through with her wishes but make it clear that you are not in favor of it, but you are going to make it appear that you want it as much as she does, and will not fight over it.
