Do you know of any instance where cheating helped a broken relationship heal or made a weak relationship better?

Has there ever been a relationship you know in which one party knew or learned of their partner cheating and it helped them grow closer either by causing the person who cheated to see what they really had to lose or what they were not gaining they thought they were, or that the person cheated on realized they were unavailable to their spouse emotionally or physically causing their spouse to feel neglected and seeking that lack of attention from another? Some even say you have to cheat to compare what you have to that you cheated with so you can appreciate what you have more. Who has known of a relationship that not only survived the cheating but caused the couples to grow stronger towards each other?
