What is it that makes remarriage challenging? The failure of a first marriage can sometimes lead people to feel distrustful and anxious about future relationships. "They may still harbor anger, resentment, or feelings of betrayal, which they bring into their next relationship," Pascale and Primavera say. "That can make it hard for them to connect to their new partner." Going through one unsuccessful marriage and then divorce can change a person's perspective and understanding of relationships. People who have already walked away from one unhappy marriage may be less inclined to endure a return to the same unhappiness when a subsequent marriage becomes rocky.
