Where Kim is concerned.. know why you're angry at her. Is it from the stalker's behavior that brought out the supreme protector mode, something you did for Kim while married?
It's good to hear she admits to mourning the loss. She's waking up. That can only help on the co-parenting front. What's wrong with saying "Uh huh, but this is the new reality. We can still be committed to what's best for our daughter." Simple and sweet. You're not her shrink.
