Days should be filled with creativity, fun, and joy to ensure they don't lose interest in each other. Sexual urges are more complicated. Many people use this excuse to justify cheating on their partner. This warning flag indicates immaturity and serious personal problems involving self-control. Another cause for cheating is dissatisfaction and unhappiness with the relationship.
People simply grow apart from the person they fell in love with.
They begin feeling they no longer share similar values, interests, goals, or beliefs. Cheating, or finding a new person, is a way to connect with someone who may share similar interests. Those with low self-esteem may be drawn to people who show them any interest at all. They may find any attention flattering since they have low self-esteem and their ego needs a boost. Before they realize all the complications and consequences of their behaviors, they may find themselves involved in an affair they never intended.
