Actually, no. None of that. The wife may stay or walk away, but she shall not make one fucking demand on the husband demanding "fairness".
This is where Western Civilization shines, does the most good. You have the freedom to walk away from a deal gone bad, but you MUST walk away from it.
None of this exists in "moral" societies, such as in religious cults where morality disguises itself in dogma, or in cultural settings where there is honor killings.
Morality is a monster.
