While a woman’s intimate premarital relationship that was exclusively with her husband did not affect the risk of marital disruption, having at least one other intimate relationship prior to marriage was linked to an increased risk of divorce (The increase in risk associated with having had a sexual relationship with another partner ranged from 53 percent to 119 percent). The risk of divorce is substantially higher if the woman not only had a sexual relationship with another man before marriage but also cohabited with that partner. (This increase in risk is as high as 166 percent).
