According to the American Association for Marriage and Family Therapy, national surveys indicate that 15 percent of married women and 25 percent of married men have had extramarital affairs. The incidence is about 20 percent higher when emotional and sexual relationships without intercourse are included.

What percentage of relationships that start as affairs last?

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.
