How do you manage a nagging husband

If a husband is nagging the question should be why is he?  What is the wife doing or better yet not doing? For the husband to constantly nag it means something is not, right? What I’m saying is a man married or not would not be complaining like that and so often if he was getting what he needed from his wife. All that nagging could very well be just because he is tired of what he expects of his wife to keep falling on deaf ears and is clearly not being heard obviously since he keeps repeating himself over and over again until he just says forget it. So, when you ask what to do about a nagging husband in my opinion that wife needs to reevaluate what she is doing and makes some changes or if she don’t think that it’s worth the effort then she needs to have a long conversation with her husband about whether the marriage is worth saving. Whatever the decision may be the nagging cannot be ignored because no one complains like that without cause or reason.
