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.
Power trips are another common reason for cheating.
Some people really believe they can get anything or anyone they want. With very little regard for the consequences of their actions, they engage in affairs and inappropriate behaviors to satisfy their own ego and power needs. Another reason for cheating is the inability to commit in a long-term relationship, commonly known as commitment phobia. Usually men have more problems with commitment than women. Therefore, men often use this excuse to justify their cheating behavior.
