Waldman’s portrait of Nate’s romantic life is sympathetic enough to have earned her fan mail from young men. But it’s precisely because Nate is sympathetic rather than toxic that the “Nathaniel P.” phenomenon — or what Rebecca Traister has dubbed “the scourge of indecisive men” — is a hard problem to escape. Indeed, it seems like one of the hidden taproots of well-educated women’s work-life-balance angst, and one of the plausible explanations for declining female happiness in a world of expanded female opportunity.

And lurking in Waldman’s novel, as in many portraits of the dating scene (ahem, Lena Dunham, ahem), is a kind of moral traditionalism that dare not speak its name — or that can be spoken of only in half-jest, as when the novelist Benjamin Kunkel told Traister that the solution was “some sort of a sexual strike against just such men.”

Because Kunkel is right: One obvious solution to the Nathaniel P. problem is a romantic culture in which more is required of young men before the women in their lives will sleep with them. 

To the extent that parents tend to see the next generation’s world through their children’s eyes, that’s an insight that’s more immediately available through daughters than through sons.
