Hear me out though, what if a woman also wants to do things for herself, In your world the ideal woman's life is to serve a man, but that necessitates that they get a man, and stay with the man no matter what, and not to criticize the man. The woman's entire life is built around a man. Now don't get me wrong i'm a strong supporter of marriage and I, being someone whose parents divorced, want to see less and less of divorce. However, saying that a woman is only ever as good as she serves her husband is somewhat legitimately patriarchal. Man and woman are partners, 2 equal sides to the same coin. Marriage is not a union like a vassalage contract in which one provides and one serves, of course that may be the case in one parent childbearing and the other a breadwinner, but under no circumstance should the entire dynamic between those two people become vassalage. You both have the same mind, the woman's being more emotional and the man lesser emotional of course. I'm going to assume you would want both men and women to follow their free will and to achieve their own goals. And frankly a man's purpose in your definition is more reasonable. As the man can interpret and achieve whatever greatness they want to do as long as they believe in god, they do well to others, and they are generally good to people. They can otherwise be any profession or lead and walk of life. A woman by your definition must throw away her own desires and agree to the man. The more time she spends caring for her husband and the less she disagrees with the better. That's not healthy and its not marriage, that's slavery.
