You need to do a bit of reading about divorce, since you claim abuse was never a fault in marriage.
That's not what I said. I'm just saying that traditionally abuse wasn't rated as highly - my evidence is that spousal rape was legal for a long, long time.
You can try to argue that spousal rape is not 'real' abuse, I guess. That there's worse abuses that earned a divorce. Okay, if it's true, it's true.
