Couples sometimes drop out of the open marriage lifestyle and return to sexual monogamy. In a five-year study of bisexuals, 80 percent of whom initially had open relationships, [[Martin S. Weinberg|Martin Weinberg]], [[Colin J. Williams]], and [[Douglas Pryor]] observed a definite shift towards sexual monogamy over time.<ref name="Weinberg, Williams, Pryor, 1995">{{Cite book |last1=Weinberg |first1=Martin S. |url=https://archive.org/details/dualattractionun00wein |title=Dual attraction: understanding bisexuality |last2=Williams |first2=Colin J. |last3=Pryor |first3=Douglas W. |publisher=Oxford University Press |year=1995 |isbn=9780195098419 |location=New York |url-access=registration}}</ref> When first interviewed, a majority of these bisexuals preferred sexual non-monogamy as their ideal form of romantic relationships. Five years later, around 60 percent had changed their views, and most of those who changed their views said sexual monogamy was their new ideal. Some of these changes were motivated by the emergence of the AIDS epidemic. Monogamy was seen as a way to avoid getting HIV/AIDS. But, for many, the shift to monogamy was due to a genuine change in what they sought in relationships. Their desire to be sexually monogamous had nothing to do with the AIDS epidemic.

Couples who try open marriages and decide to return to sexually monogamous marriages may be left with different feelings about open marriage. Some may have negative feelings about their open marriage experiences.<ref name="Gates, 2002">{{Cite book |last=Gates |first=Jennifer |title=Survivors of an open marriage |publisher=KiwE Publishing Ltd. |year=2001 |isbn=9781931195188 |location=Spokane, Washington}}</ref> Others may continue to "see nonmonogamy as possibly good for others but not for themselves".<ref name="Weinberg, Williams, Pryor, 1995" /> Overall, open marriage has a relatively neutral impact on these couples.  Rubin and Adams did not observe any difference in the risk of divorce for couples in open marriages and couples in sexually monogamous marriages.<ref name="Rubin, Adams, 1986" />
