How long do marriages last after an affair?

A study conducted by the American Psychological Association showed that among married couples who experienced infidelity but then underwent couples therapy, 53% were divorced after 5 years. By comparison, only 23% of couples who did not experience an affair were divorced after 5 years, which is a huge disparity.

According to WebMD, the “in love” stage of an affair lasts 6 to 18 months, on average. And around 75% of the marriages that start as affairs end in divorce. Considering only 5 to 7% of affair relationships lead to marriage, thats a grim statistic for couples hoping their affairs will last forever.
