When Bill and Melinda Gates announced their divorce in 2021 after 27 years of marriage, many people were surprised. Long marriages often appear stable from the outside, especially when couples have built families, careers, and shared accomplishments over decades.
Yet divorce is still a common experience in the United States. According to Pew Research Center’s analysis of U.S. divorce statistics, more than 1.8 million Americans divorced in 2023. That reality leads many people to ask an important question: why do couples divorce after decades together?
Studies and personal accounts suggest several common patterns that help explain why long marriages sometimes reach a breaking point.
Growing Apart Over Time
One of the most common explanations outlined in a Psychology Today article is simply that couples grow apart and people change:
• Careers evolve and priorities shift
• Personal interests develop in different directions
• Individuals may develop new goals later in life
Years of Quiet Dissatisfaction
Divorce after a long marriage is rarely a sudden decision. Many people report that problems existed for years before the relationship finally ended.
• Couples may stay together for the sake of children
• Financial concerns can delay separation
• Some people hope problems will eventually improve
Research and counseling experience often show that dissatisfaction can build slowly until one or both partners decide the relationship can no longer continue.
Major Life Transitions Can Change a Marriage
Additional research also indicates that certain life events can dramatically reshape a long relationship. Moments of transition often lead couples to reevaluate their future together.
• Children leaving home can change daily routines and shared priorities
• Retirement may reveal different expectations for lifestyle and travel
• Health concerns or aging may shift personal perspectives
When the structure of family life changes, couples sometimes discover that their goals for the next stage of life no longer align.
Changing Expectations About Marriage
Modern relationships often carry different expectations than marriages did decades ago.
• Many people today prioritize emotional fulfillment and personal happiness
• Social attitudes toward divorce have changed significantly
• Individuals may feel more comfortable leaving relationships that are no longer satisfying
Psychologists note that evolving cultural expectations around relationships have influenced how couples evaluate their marriages and long-term happiness.
People Are Living Longer and Reassessing the Future
Another factor behind divorce after long marriages is simple longevity. Many couples today can expect to live decades after retirement. According to recent life-expectancy data from the U.S. Centers for Disease Control and Prevention, life expectancy in the United States rose to about 79 years in 2024, continuing a rebound after pandemic declines
• Someone in their 50s or early 60s may still have many active years ahead
• Individuals sometimes reassess how they want to spend the next stage of life
• Some decide they would prefer to pursue those years independently
Planning Carefully After a Long Marriage
When a marriage ends after decades together, the legal and financial issues can be particularly complex.
• Retirement accounts and pensions may need to be divided
• Long-term assets such as homes or investments must be addressed
• Spousal support may be a significant consideration in long marriages
Because these marriages often involve decades of financial planning and shared assets, careful legal guidance can help ensure that the transition is handled thoughtfully.
