It’s an underlying problem not often discussed. Women will confirm it if asked, men will usually deny it or be defensive about it. Typical reasons men give include, “My wife knows I love her, I don’t need to say it to her every day” and “If I go soft, she’ll take advantage of me.”
The truth is that most men either don’t understand women at all or completely patronise them.
If a man wants to be happy, he has to make his wife happy. And to do that, he has to know her, understand her needs, and meet them.
