Final answer:
The scenario described refers to the evolving societal views on marriage and relationships, where non-traditional structures, like cohabitation, are becoming more accepted, and women find security and happiness in singlehood, especially when successful in other aspects of life.
Step-by-step explanation:
The concept described in the question does not have a specific term but relates to changing societal views on relationships and marriage. Traditional U.S. family structures are becoming less common, with trends indicating an increase in cohabitation and single adults living without a permanent spouse. For many women, there is a sense of security and happiness in being unmarried, particularly those who have succeeded in education and careers. Additionally, societal attitudes are shifting, with less stigma attached to cohabitation and non-marital relationships.
