If you can't co-parent, can you save a marriage?

If parents have completely different styles of parenting and neither can agree on how to raise their kids, can a marriage work? Assume one is always yelling and swearing at the kids and one is more laid back about discipline. If the parents split up, the kids would still be raised differently while in each of the parent’s homes. So I assume the only upside would be no more arguing/toxic environment at home anymore. In my experience, people don’t change drastically, even if they have the best intentions to. So let’s also assume the parenting styles will remain the same. How could this ever work? Seems like a lot of resentment would build.
