A new study by UCLA psychologists is the first to examine premarital cold feet – the concept of having doubts before getting married – and its effects on the longevity of marriages. The study focuses on whether those premarital jitters people often experience should be heeded or ignored, and the consequences of making those big, life-changing decisions like marriage or separation. Check out the review of the study here, which includes this line: “Doubts don’t evaporate; they’re suppressed, only to return later.”
