Your piece of work is too economical of words. You would have stated the obvious. But that would not stop me from contributing my ideas.
Marriage perse is a Divine contraption contracted by God almighty. So no person could put it apart except death. I'm coming from the christain perspectives. Though the couples come from different background, God has the ability to unite them together, and such unity is binding for life.
But where there is a disagreement between the two, major or minor, leading to divorce, reunion is permissible by the Almighty God. So what God allows, no societal ordinances could contravene, it becomes null and void in it's entirety.
