The answer seems to be common sense. Ask anyone about whether having an affair affects marriage and they will likely say that infidelity is severely damaging. So what has been the view of family scientists and clinicians?
Until very recently, there was a general belief among family scientists and clinicians that extramarital sexual relationships had little impact on whether or not a couple divorced. Huh? Why is that? Many scientists view extramarital sex as the result of a marital relationship that is already in bad shape. In short, extramarital sex isn’t the cause, it’s the result. Also, clinicians who work with couples in which there has been infidelity report moderate success in helping couples overcome the issues associated with an affair. In other words, for some couples, the affair prompts them to deal with marital issues and improve their relationship.
Most of the past research indicates that extramarital sex has little effect on divorce. However, a closer look at the research indicates that there are significant flaws in the samples of couples studied that raise doubts about whether these findings can truly be generalized to American society. But recently, Elizabeth Allen and David Atkins analyzed data from 16,090 individuals than gives some new insights into this issue.
