The reasons why women don’t wind up with the families they wanted, taken one by one, may seem random or like bad luck. But there are patterns. Women blame themselves, ignoring the fact that their decisions are not being made in a vacuum. Wanting a career you love isn’t bad. Wanting to be stable financially before you have a child isn’t bad. Wanting to have the right partner isn’t bad. Unfortunately, sorting all these things out takes time. And women have many fewer fertile years than men, who can father children well into their fifties.
