Women don't have children any more than men do.
Couples have sex, couples get pregnant, couples have children. . . .
And a father loves and cares and nurtures as much as any mother, however much in his own way. But even when you do not believe that, it is what our social conventions impose. If it isn't true in your life, it should be. Divorce should be an opportunity to set that right, not eliminate it. It will help you overcome them in your own mind, and give you something to take to the lawyers, judges, and social workers who would treat you like you are less of a parent than you are.
