Biological anthropology professor at Rutgers University, Helen Fisher, who has written five books on the future of human sex, love, and relationships, says that marriage has changed more in the last 100 years than the previous 10,000, and it could change more in the next 20 years than the past 100!
We're shedding traditions that have survived since our culture began 10,000 years ago, Fisher says, and it appears we're returning to the ancient sex and romance practices of our hunter-gatherer days.
Concepts such as, 'till death do us part, a woman's place is in the home, and men as the primary wage earner, began disappearing in the last half of the 20th century. Today, relationships are undergoing huge changes. Divorce is viewed more as a solution than a shame; working-women are now the norm; living together without marriage is gaining popularity; and some states have legalized same-sex weddings.
In addition, our concept of infidelity is also changing. Some married couples agree that it's OK to have brief sexual encounters when they travel separately; others sustain long-term adulterous relationships with their spouse' approval. Even our view of divorce is experiencing major transformations. Ending a marriage used to be considered a failure; now it's often deemed the next step toward true happiness..
