#1 quality, fertility. That is if he wants children. What most men don't realize is that we can get about anything we want in life by being successful. The mating dance humans display is extremely complicated. It is further complicated by a woman's deception. The right clothing and makup can turn an ugly duckling into a swan. The exposure of the Hollywood casting couch is a good example of how both men and women manipulate each other. An ugly producer gets another notch in his headboard and a starlet gets a million dollar contract. I think that this example is played out in many relationships. There's a reason they call it the oldest occupation. Not to say that both participants don't benefit from an equitable arrangement. Both have a more secure existence if a true commitment is made. I wish I knew all of this when I was younger, perhaps I did but the delusion of romantic love clouded my thinking and the desire to reproduce fed that flames that ended up burning up us both. The state contract is easily broken and in the end probably cheapens the commitment because both parties know this.
