Males and females are not symmetrical. A female who never reproduces because she wants to be faithful to a mate who doesn't exist is giving up 100% of her reproduction. A female who stays faithful to a mate who does exist is giving up 0%, in terms of quantity -- one mate can provide all the children a female is capable of having.
