Cohabitation refers to the act of living together in a romantic and/or sexual relationship without being married. This research area focuses on studying the dynamics, challenges, and outcomes of couples who choose to cohabit instead of getting married. Researchers examine factors such as relationship satisfaction, commitment, communication, division of household labor, financial arrangements, and the impact of cohabitation on relationship stability and longevity. Cohabitation is a common living arrangement among couples in modern society, and studying this phenomenon can provide valuable insights into the changing nature of intimate partnerships.
