Divorce Predictor #14: You are a female serial cohabitator.

Women who have lived with more than one partner before their first marriage are 40 percent more likely to get divorced than women who have never cohabitated prior to marriage. Although cohabitation seems like good practice for married life, it can tend to make living together during marriage seem less permanent. According to the Brown University Population and Training Center, a marriage preceded by cohabitation has a better chance of success when the couple became officially engaged prior to moving in together.
