I think she tries to over compensate for a world that blames men for everything. Although she seems to have jumped the shark here.
Why do you say that? Saying that women share some of the blame for husband who stray isn’t absolving the husbands of wrong doing, any more than saying abusive parents contribute to delinquency doesn’t absolve the delinquents from their wrong doings.
All she’s saying here is that wives are not helpless when it comes to adultery, that often they have the power and the ability to affect their husband’s actions, instead of being helpless victims, they can take certain actions that can help prevent their husbands from straying.
