It's a bit counter to DB, but I liked the notion that her H was going to have to explain to the kids why he was leaving.....and not her.
I also liked how she explained to ow that she would always be a part of him.
I don't think it's counter to DB at all. This doesn't constitute confronting H, whining, or anything of that sort. H must take responsibility for his actions. Nblost doesn't have to actively participate in anything that runs counter to her beliefs. If she were to do so, she’d be taking responsibility for his actions. Nblost only has to take responsibity for her actions. I think that’s why MynameisMZ “likes the notion.”
Dunno about talking to OW, though. It may have felt good to say it, and it probably didn’t do any harm, but I think I’d avoid making a habit of it. If you engage her, then it could bring them closer together as a team.
