People cheat on their partners for different reasons. Often, when one partner feels that he or she has been neglected by the other for a long time, they end up hanging out with other people they are attracted to which sometimes leads to an adulterous relationship. In a simpler term, the crave for attention can lead to cheating should one partner feel neglected by the other. Some also cheat on their partner due to the inability of one partner to satisfy the other in bed. A relationship is usually the haven for sexual activities, hence if there isn't any sex going on or there are several issues with performance in the bedroom, this can trigger cheating.
