I told her how impressed I was with her maturity. She understood a principle that many seem to miss: Vengeance leads to bad decisions, and bad decisions lead to bad consequences. Vengeance attempts to make the other person hurt as badly as you hurt. It never fully satisfies because you can never be sure that the other person hurts as badly as you do.
Demand justice, but forego vengeance. Vengeance may hurt the other person, but the emotional damage it does to you may be far worse. Collateral damage, such as the long-term effect on your children, financial stress, or dividing your mutual friends, may well be the worst of all. Vengeance usually hurts the vigilante more than the intended target.

If you intend to hurt the one who hurt you, you will not make a wise decision about whether you should divorce or reconcile. If you wish to make the best decision for your future acknowledge your hurt, but do not let your pain cloud your judgment. Make the choice that benefits you, your children, and your future, rather than a choice that ultimately hurts you more. To do that, acknowledge your hurt, but do not focus on repaying the hurt.
3. Consider your spouse's heart. A woman sat in my office after discovering her husband's infidelity. She talked about how her family, especially her father, wanted her to divorce her husband and, in the process, punish him severely for what he had done. After we talked about the danger of heeding advice from family and friends, and the detriment to her own heart and soul if she sought vengeance, I asked her a question.
"Is he a bad man who did a bad thing or is he a good man who did a bad thing?"
She enquired as to why I would ask that question. I explained that good people sometimes do bad things, but that if they are at heart still good people, they may be worth rescuing. Good people who regret bad behavior and want to make things right tend to be better people than they were before their indiscretion.
"So," I asked, "Is he a good man worth taking the risk to rescue, or a bad man that you should get away from and stay away from for the sake of you and your children?"
