I agree with that. But I also think (and I believe the studies confirm this) that kids generally do better in households where the parents self-describe as "unhappily married" than they do in households where the parents have split up. Years ago, people used to "stay together for the sake of the children." More recently, in the age of ME/MYSELF/I, they decided that was too stressful and rationalized their behavior by claiming the kids were badly affected by their own unhappiness. Maybe, maybe not. But almost always, the kids get hurt much, much more badly when their parents divorce.
Yep, I get your point.
