RE: Shut your mouth and let him talk!
This was interesting, although I am not sure I agree with the one of the message. I preceive this post as blaming your friend, the woman, as the one 'causing the trouble by emasculating her husband. If there is any trouble, the blame could go onto two ways: the communication, or the society and gender stereotypes, evident in your writing.
Some men do have fragile egos, yes. Not everyone is good at everything, and not everyone accepts that. I know you say that women need to listen to men more, but, at the same time, the men have to speak up more. From personal experience, I know that a lot of men like to stay silent and struggle alone, without wanting to be perceived as wrong or weak - and this is at large a societal issue not a family's.
Furthermore, there is always going to be a problem if you look at a husband and wife differently, as a man/woman of the house etc. That language belittles the person to just one role, and when they do not live up to the role's expectations, there is more trouble. It is much better to consider the other person as a partner. A crime partner, a business partner, whatever - you are both equal. You have to take the heteronormative gender words out to truly value the other as an equal.
