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.
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.
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.

In a different story, the husband found out his wife was cheating. He focused on bettering himself. He started going to the gym, got a promotion at work, and became more involved in hobbies.

One possible story could be that the husband found out his wife was cheating. Instead of getting angry immediately, he quietly gathered evidence. Then he used that evidence to expose her affair to her family and friends, which was his form of payback.
One common motive for revenge in such stories is the sense of betrayal. When a man discovers his wife is cheating, he feels deeply wronged and wants to make her feel the same pain. So he might expose her secrets or cut her off financially.
Some men might choose to take revenge in a more emotional way. They could write a detailed letter to the wife's family about her actions, not in a spiteful way but more to let them know the truth. Or he could start dating other women in a very public way, not to be unfaithful himself but to show his wife that he has moved on and is desirable to others.
