Women are interested in better than average odds of survival. They re using everything they have (intelligence, beauty/ mind, physique) to obtain it, to find the man that will provide them with these better than average odds of survival. And men do exactly the same. They want trophy wives and work to sustain a family, they re designed by nature to do so. Failing to do so leads to frustration and anger. Being sucessful at doing so leads to what humans call hapiness.
Women want men who will take care of them and eventual offspring just like females do in any other animal specie. And men are designed by nature to study, work, and provide ressources to female and offsprings until offsprings are ready to continue the lineage after accumulating all the knowledges given to them by their caregivers, which will increase their own odds of survival against their peers inside the specie, and against predators and the environmental phenomenons. Nowadays humans have no more predators, so they only fight each others for domination, survival. Our brains are computers that calcultate how to adapt until we spawn an offspring. Then they calculate how to insure and increase its odds of survival. This is the circle of life.
Women are satisfied when they know they have the maximum they can obtain depending of their physique and intelligence. As do men.
They are frustrated when they think they could get better than the man they re with. They might try to improve him, or fail to do so. Men also might want to improve their women, can be sucessful or fail. When both man and woman follow the same life's guidance (The Bible) they re united and following the same path together, bettering themselves on the way, and maximizing the odds of survival of their offspring giving it their maximum. They also automatically unit with others parents, families, who follow God's words. And they re in oposition with atheists, homosexuals, muslims.
We are constantly at war with ourselves, with our past, our present and future. Genders , races, are at war with each others. Welcome to the animal kingdom. Peace is found in a stable situation where men give their maximum potential in the best job they could obtain depending of their capacities. They can raise an offspring with a woman who stays in shape, work part time and genuinely takes care of both kids and Man. Then we age, we lose everything slowly and to compensate we teach our offsping how to survive, which in return produces hapiness in our brain.
Life has no other purpose but to encourage life, ie its constant perpetuation / adaptability. Adapting, surviving, comparing yourself to others in your race, species, who have harder odds of survival than yours, is what makes you feel happy. Failing to adapt, failing to seduce, failing to build a family -after seducing a mate-, is failing at living and fulfilling our purpose.
