Are there certain situations where the henpecked husband or the nagging wife depicted in many of today's movies and TV shows are actually an abused husband dealing with an abusive wife?

On TV, it seems really funny. In real life, it is hurtful, annoying, and frustrating. It can be abusive if it is constant and there are insults added to the nagging.

'Nagging' is mainly about reminding people to do things that they ought to do. If it's agreed in your household that you mow then lawn and you haven't done so, and it needs doing, then your wife is perfectly entitled to remind you of your duties. (That said, there's no case for her being gratuitously offensive about it).

However, if your wife habitually goes out of her way to find fault with you, to put you down and bully you, then it's very bad.
