“Furthermore ,there were many marriages in the past that [we would call] abusive that were not so happy, but raised wonderful children and have wonderful descendants”
Maybe so, but in today’s age, children raised in abusive marriages have a high probability to go on to be abusive or abused themselves. I’d say better to break the cycle and find a different way to raise wonderful children and wonderful descendants.
“it was through those means that greater glory was gained for all “
Not a Torah concept!
