Sure, but in fairness I think that the intent of that saying is not to say that husbands should not be happy but to counterbalance the trend that used to be more historically prevalent in marriages for the wife to be treated as an appendage of the husband and taken for granted. If you view your partner as co-equal then arguably this saying simply does not apply to you at all.
I have never, ever heard it uttered by anyone except a married man who definitely meant it to mean "Give in to her every demand as written at any cost and you might have a moment of quiet."
I went out to drinks with older coworkers earlier in my career, and each time it was just constant wife bitching. Oh she does this, I hate that, old ball and chain. They came to me, I was in a long term relationship (who I'm now married to), and I just didn't have anything to share. Things were going fine. They laughed and said you just wait har har har.
Well, that was 10 years ago now. We're happily married, our marriage is full of compromise and mutual respect. We have tiffs, but never full on screaming matches. I still don't have anything major I'd share at a bar.
Them though, 3 of the 4 of them are now divorced. Maybe spending all of your time at the bar complaining about your wife wasn't the best for your marriage. But honestly too, good. If you hate them, why the hell are you married?!
Maybe staying at home and talking to each other about those complaints would've helped to work them out and compromise. Bitching to your buddies can be a good release, but it doesn't help solve anything.
Never go to bed angry is in here too. You can see why if you also know that nothing good happens after 2AM. Sometimes you just gotta sleep whether you're kinda mad or not.
