It’s never 50/50! My point is that except in the very extreme examples you cite both parties are at fault to some degree and to imply to the children that only one person is to blame is in my opinion dishonest and does not serve them
My examples aren't that extreme.A lot of people have a problem with monogamy these days.And don't take marriage that seriously.
Like i said, no such a thing as a perfect spouse exists, but even if you aren't 'blameless', that doesn't mean you didn't contribute far more and fought harder for the marriage than your counterpart.
No one's without sin, but some people contribute more to society than others.
