As a wife myself, I responded with my heart. How WOULD she feel if she knew how he was posting about his other half? I'm sure he can make his point without calling her names. He's done it several times although the name has been left out. Yet, we know what goes in the blank, don't we?
An attitude change or a different perspective is direly needed, IMO, both about his wife and himself.
