No, she can be sorry and still go through with it. The two are not mutually exclusive. You can tell her that's not your preference but you are going to move your life forward in a positive direction regardless ...
Doesn't that give the impression that I approve of the divorce?
Here's the thing, right now you're pushing your agenda, what YOU want. Every time you do it reminds her just how far apart the two of you are and it drives her farther away from you. It makes her more anxious to pursue D. Stop pushing YOUR agenda on her. She KNOWS you don't want D, you don't need to keep reminding her. What she's going through right now is all about her. You need to listen and validate and that is it. Don't tell her your feelings, don't argue/ beg/ plead/ negotiate/ agree/ disagree. Just LISTEN and VALIDATE. Take all the pressure off of her. No R talk. No M talk. Once you remove the pressure from a WAS they often no longer feel the need to push for D.
