The cheating spouse often feels guilty, but for most who get caught it is not because they feel sorry for what they did, but angry that they were caught. Some spouses may feel they are stuck with their mate or, the victim of cheating may not want to grant a divorce so the cheating spouse may push and shove to make life miserable for the victim of cheating and force them to divorce them.
