Thanks for this Tracy (and for linking to the work of my co-author, Susan Pease Gadoua). My comment on that Modern Love column:
Stop judging/shaming Josh and Elizabeth’s actions and start embracing the fact that people are capable of parting in a way that is loving and kind. Studies show it isn’t divorce per se that hurts kids — it’s conflict. You may not approve of this family’s new configuration and you may not want to have that kind of configuration for your own family, but please — focus on the fact that the girls will have more people who love them and less conflict among them. That’s really all that matters here.
