I suppose you have heard the phrase here about "I won't resist, but won't assist" when it comes to a WAS's decision to D.
I hadn't heard that before! That's a good one!
My gut feeling is that she's still working towards D and that she is hoping to keep the house somehow. But good at least that was a little chink in her fantasy bubble and a little reality check for her.
I think when she gets enough reality checks at some point she will want to R with you and work on the M. You just have to try not to shield her, comfort her, and let her experiences consequences/reality. My concern would be that the longer it takes, the less likely you may be interested in R with her!
