One story I heard was about a woman who found out her partner was cheating. Instead of making a scene immediately, she quietly collected evidence of his affairs. She then sent an anonymous package to his workplace with all the proof, which led to him getting fired and his reputation in tatters.
A wife found out her husband was cheating. Instead of crying or making a big scene immediately, she started leaving little 'gifts' around the house for the mistress. Things like really ugly sweaters and old, used shoes. When the mistress finally came over and saw all those things, she was horrified and left the husband. The wife had a good laugh seeing the chaos she caused for the two cheaters.
A wife cheating on her husband in a revenge novel usually involved the following plot:
The protagonist was cheated on by his wife. He felt angry, disappointed and desperate, and decided to take revenge.
Through various means, including investigation, stalking, threats, etc., the protagonist finally succeeded in exposing the truth of his wife's adultery, making her feel guilty and ashamed.
After revenge, the protagonist would usually seek inner balance and repair, try to communicate with his wife and try to forgive her mistakes.
In some novels, the protagonist may choose to divorce or take other actions to end the marriage, but after revenge, he will usually reconsider his life choices and start a new life.
This kind of novel usually involved topics such as love, marriage, family, morality, etc., which might bring readers deep thoughts and enlightenment.
One way some might think about revenge is through public shaming, but this is unethical and can have legal consequences. A more proper approach could be to gather evidence in a legal and respectful way if there are matters like alimony or child custody to be sorted out in case of a divorce.
I don't know exactly who said it. It could have been a protagonist who came to this realization after going through a series of challenges and learning lessons about the futility of revenge.
One idea could be to expose his cheating to all his friends and family. This would damage his reputation. Another could be to get involved in his work life in a way that makes things difficult for him, like if he has a project coming up, you could find a way to disrupt it subtly. But remember, revenge might not always be the healthiest option in the long run.
One way could be to expose her actions to her family and friends. Let them know what she has done in a calm and collected manner. This can make her face the consequences of her actions within her social circle.
In a story, the husband who has been wronged by his cheating wife might decide to take revenge by writing an anonymous and very steamy novel about a woman who cheats on her husband and the karmic revenge she faces. The erotic elements are in the detailed descriptions of relationships and encounters in the novel, which becomes a huge bestseller and embarrasses his wife as everyone speculates it's about her.
