^^^ What he said.
Not to mention the fact that many many women didn't have the option of divorce back in the day regardless of how much the marriage sucked.
Divorce is actually a good thing in many circumstances.
Bottom line is new age/old school matters not. What matters is the morals and ethics of the two involved in the marriage. There is nothing that could penetrate the fortress that a couple creates when they commit to each other with marriage, that is unless one or both ALLOWS it. But even then if the foundation is solid the fortress can be repaired/rebuilt better and stronger than ever before. But only if BOTH want it badly enough.
There is no such thing as impossible, but rather only that which we CHOOSE not to do.
