A decent person does not alienate children from a parent, no matter how angry they are at the parent for the divorce. It's unfair to the children, and it's unfair to the other human being
I have long believed that what most affects a child is not the divorce, per se, but how it is handled
Nothing provides the antidote to narcissism, or the environment for the healthy raising of children, or the way for people to take care of one another, as does the marriage of a man and a woman. And while most divorces are terribly sad, divorce itself no more undermines the institution of marriage than car crashes undermine the institution of driving.
