Agreed. If we’re talking inconvenient truths, I see far, far more husbands being useless married (and particularly parental) partners than I do wives. And I say this as a man.

I’m assuming “initiated by” is an objective legal term for filing the divorce. which ironically is probably oppositely correlated to fault in divorces, i.e if the husband cheats, the wife files for divorce, and it was the husband’s ‘fault’ as they breaches the marital contract

The figure comes from interview data of post-divorce couples regarding motives for divorce (and a few other questions, i.e. regret etc). It's not literal paperwork filing data.

I'm fairly sure they meant entirely the opposite.
