Though many assume moving in together is a logical step toward a stronger marriage, decades of research reveal a startling and consistent paradox: couples who cohabit before marriage face significantly higher risks of divorce and lower marital satisfaction compared to those who wait.
Key Takeaways
- In a longitudinal study of 1,294 couples from the National Survey of Family Growth (1985-2015), women who cohabited with their future spouse before marriage had a 33% divorce rate within 10 years compared to 23% for non-cohabitors
- Teachman's 2003 analysis of NSFG data (1970-1995 cohorts) found premarital cohabitation increases marital dissolution risk by 48% for women with one partner
