I've watched someone in my life leave his wife because she was infertile. It's probably a good reason why I heavily doubt so many of the I'd never leave her answers tbh so I'm likely very biased about this.I think many of you have never been married. Once you're emotionally and spiritually committed to a woman, you would never divorce her because she really becomes part of you. If both of you can't have children, you (the man) have the option of marrying a 2nd wife provided you aren't the one who is sterile.
Fyi, I am not naive that people divorce but not able to have children should not be part of it.
