There are several reasons why second marriages can be more vulnerable to disruption. Partners bring the same personal qualities to their subsequent marriage as they had during the first, but some of these qualities may have contributed to the first marriage’s problems. People who have divorced and remarried multiple times tend to be relatively impulsive and nonconformist. In second marriages, partners also often have to deal with additional complications that do not exist in first marriages, like combining families. Remarriages involving stepchildren have a greater rate of dissolution than those without.
