If you ask me, that's the real treachery. Stringing a woman along about something as fundamental as having a child. If she stays with him, how does she tap down the resentment, if not now then later on?
I've never read about a woman whose partner refused to have a child and later on that woman was happy about it. But I have read stories about women who got pregnant on the sneaky and later on, their partner was happy about it.
