Getting that percentage measured correctly would require a different type of sample and method. Closely related to that question, Galena Rhoades and I found in a previous study that 16 percent of those followed into marriage in the study’s parent project reported that they had cheated on their eventual spouse sometime before their marriage.[viii] In this new study, 45 percent of individuals who reported cheating on their partner in the first relationship reported also doing so in the second. Among those who had not cheated in the first, far fewer (18 percent) cheated in the second. While the odds of cheating on a partner were far greater if one had done so in the past, a person cheating in one relationship was not destined to do so in the next. In fact, slightly more people who had cheated in the first relationship studied did not report cheating in the second. cloudgeeksync@gmail. com cloudfoneclone. com
