Marital Happiness Improves Over Time

study examining 20 years of data, discovered multiple factors that contribute to long-term marital happiness. Researchers found that a belief in lifelong marriage, high religiosity, shared decision-making and shared housework increased the odds of high happiness and low conflict in marriage.

According to new research, marriages that remain together for more than 20 years also experience a return to initial levels of happiness, continuous declines in discord and increased shared activities.
