What Percentage of Affairs Lead to Divorce
Research suggests that infidelity is a factor in roughly 20 to 40 percent of divorces in the United States. Not every affair results in divorce, but studies consistently show that extramarital affairs significantly increase the risk of marital dissolution. The exact percentage varies by study, population, and how divorce is measured.
Why Some Affairs End in Divorce and Others Do Not
Divorce is more likely when the affair is long-term, secretive, or emotionally intimate. Couples with strong communication skills, willingness to seek therapy, and mutual commitment to rebuilding trust may stay together. Other factors include the reasons for the affair, prior relationship satisfaction, and whether both partners choose to address the breach of trust.
What the Data Sources Say
Large-scale surveys and marriage research organizations provide estimates on infidelity and divorce rates. For example, the American Psychological Association and other research bodies have published findings on the link between extramarital affairs and marital breakdown. These sources help contextualize the numbers and show that while affairs raise divorce risk, they do not guarantee it.
