Ever since I heard word of my aunt and uncle getting divorced (two people who have been together since I can remember) I started wondering if human beings are really meant to stay with one other person till death. My parents are divorced after 20 years, I've seen relationships die after couples being together for years, and the divorce rate in America is 50%. It makes me wonder considering the physical goal of male humans is to spread the genetic seed as much as possible, does it do our species any good to just stay with one partner till death?
