The Evolution of Marriage

One thing that makes me wonder constantly is why and how are men and women different. Why do women like to make fun of men and vice versa? Don't they need each other to get to a common goal? Why do many women believe that Orthodoxy lowers women and make them into slaves? I have no explanation for it. It seems illogical to me. Even on an emotional level. Marriage in my short opinion, is a male and female creating and evolving a friendship to create a spiritual entity called marriage. It is something divine. Beyond nature. It is a deep love and coming to understand each other intimately to grow into a human. Beyond instinct and desire. To become a single machine to do the bidding of God. Children are the manifestation of this goal. A child combines both parents and God. When it grows it is taught to do goodness and kindness so the new entity will come close as possible to God. Love must be constantly work on. A man should not be stingy with his money. He should always give money to his wife with a smile. A wife should always try to find ways to cheer up her husband. She is not required to study torah. She will not be asked did you do your business honestly or did you set aside time for learning. She will be asked though, "Did you make your husband happy?" "Do you know what his favorite foods are?" A man will be asked did you make your wife happy by buying her jewelry and nice clothes. This is what Orthodoxy advocates, is there anyone who can suggest something better?
