Cheating is stressful. It requires someone to keep their stories straight and provide attention to more people. This can lead to a cheater being in bad moods. If they are prone to abuse, they may become increasingly abusive. This is also done to exert a measure of control over the person being cheated on. If you are afraid of being beaten or being deprived of basic necessities, you will be less likely to accuse a cheater of committing infidelity. Stress related to the cheating may also lead a cheater to be increasingly abusive towards children as well. Children are sometimes considered to be the only reason a parent stays in a relationship. This can lead to resentment and retaliation against the children.
