The Thinking Housewife talks about married couples who choose not to have children.
There’s a personal aspect to this. Lots of women say (and no doubt believe) that they aren’t interested in having children, until they find a guy they’re enthusiastic about. The pretence (and even the self-deceptive acceptance of your own pretence) is a normal part of relationship negotiation—in particular, a woman doesn’t want to seem too eager. But if you’re married and your wife still doesn’t want to have your children, then she just doesn’t love you.
