There are many reasons why people cheat, and the patterns are more complex than common stereotypes suggest. In the end, only a third of participants ultimately admitted the cheating to their primary partner. On the other hand, situational cheaters were less inclined to cheat out in the open, perhaps because they hoped to return to their primary relationship without getting caught. Ultimately, the fate of the participants’ primary relationship depended less on the act itself and more on what motivated it. Surprisingly, only one in five (20.4 percent) of relationships ended because of the affair.
