Sometimes when the relationship is already long some people are too complacent already about themselves. However, there certain things which could potentially ruin the relationship. Women cheat because they are attracted to another guy and they also cheat because they want to reaffirm desirability. On the other hand, men cheat because they expect more intimacy in the relationship and apart from that they simply wanted to try having a relationship with another woman. Hence, this becomes the reason why divorce rate has gone higher and higher each time.
