Why do husbands do what their wives say?
Because many people in the US, in particular, believe some wild mantra of happy wife = happy life.
But what if the point of marriage is more about fulfillment than happiness? Now, I'll be the first to admit that my wife is incredibly supportive of the life I'm living (overall). So if she's happy, then she might be more supportive. But if she's not happy, is that my job? Or should she, as a grown woman, learn to find joy and contentment in her own identity? Yes. I want that. It's incredibly codependent to believe oneself to be responsible for the happiness of another.
I want her to have her own dreams and vision of a future. Sure, with me. But not because of me.
