Yes but can’t hedging against a bad marriage actually be a lack of commitment to a marriage? Like having one foot out the door?

For example, should a man keep in touch with old girlfriends to protect himself from being emotionally trapped in a bad marriage? (Obviously not - but why is a woman having her own job outside the home so different?)

The needing each other to survive and committing to each other no matter what is the important part and if you take that away, marriage is just another relationship (and you see this with the rise of the vague term “partner” for even heterosexual relationships - people are too non-committal to even using specific language about the deal)
