Cheating can destroy a marriage, but sometimes it also reveals exactly where everyone else in the family stands. I think there is something strangely comforting about discovering that the people you expected to defend their own son are instead willing to call out his behavior and support the person he hurt.
One Redditor found herself in that unexpected position after learning that her husband had been unfaithful. Even though the couple was heading toward divorce, her in-laws still moved into the family home as originally planned, and they made it clear whose side they were on.
The tension grew when the husband allegedly lied to his mother for money and then spent the next day with his mistress. That small betrayal pushed his mother over the edge and inspired a delightfully petty form of revenge involving dinner. Scroll down to see how this unusual household handled the fallout.

Divorce doesn’t necessarily divide an entire family neatly down the middle.
Parents can love an adult child while strongly disapproving of that child’s behavior, and former in-laws can develop bonds that exist independently of the marriage that originally connected them.
Psychologist Joshua Coleman has written about how divorce can create complicated loyalty conflicts for extended families, including situations where parents genuinely love a son- or daughter-in-law they may lose when their child’s relationship ends.
A Psychology Today discussion of parents coping with their children’s divorces specifically notes that “loyalty issues surface too” because relatives may have formed meaningful attachments to the spouse and grandchildren.
That helps explain why the mother-in-law’s reaction doesn’t have to mean she stopped loving her son. She may simply have reached a point where supporting him no longer meant defending what he did.
Infidelity itself can create profound emotional upheaval. Researcher Mark Whisman and colleagues found in a population-based U.S. sample that the annual prevalence of marital infidelity was about 2.3%, while other research has linked discovering a partner’s affair with substantial psychological distress.
The exact rates vary considerably depending on how researchers define infidelity and which population they study, so no single number captures every relationship.
The Gottman Institute describes affair discovery as a form of betrayal that can bring anger, sadness, fear, and a sense that the reality of the relationship has suddenly changed. Its affair-recovery guidance stresses accountability and says the betrayed partner needs their feelings heard and validated rather than minimized.
That validation seems important in this story because the wife wasn’t receiving it only from friends. Her husband’s own parents were acknowledging that his decisions had consequences.
The $20 lie adds another layer. The American Psychological Association reports that money is already a significant source of relationship tension: in one Stress in America survey, 31% of partnered adults said money was a major source of conflict in their relationship.
Here, the amount was tiny, but the perceived deception made it symbolic. To his mother, the issue apparently wasn’t twenty dollars. It was discovering that her son may have manipulated her generosity to support behavior she already opposed.
As for the revenge dinners, they fall at the wonderfully low end of the retaliation scale. Nobody is destroying belongings or sabotaging finances. Two adults have simply stopped organizing every household meal around a grown man’s picky preferences.
That may even represent a healthier shift than calling it revenge suggests.
After 15 years of accommodating his tastes, the soon-to-be ex-wife no longer needs to structure her domestic labor around keeping him comfortable.
Psychology Today guidance on marital boundaries emphasizes autonomy, communication, and deciding what responsibilities people are willing to take on for one another. Once a marriage is ending, continuing spouse-level caretaking can blur an already complicated transition.
For this family, the most constructive future probably involves reducing the petty games as the separation progresses, keeping financial arrangements transparent, and protecting the daughter’s stability from adult conflict. The wife already seems to be moving that direction herself: she admitted she barely cares about revenge anymore.
That may be the strongest part of the story. The meals are funny. Indifference is freedom.
Here’s how people reacted to the post:
These users celebrated OP’s progress and praised her supportive in-laws
These commenters saw the ex as little more than a roommate who should move out
This group felt living well, with the in-laws backing OP, was the sweetest revenge.
This Redditor joked that OP should keep the wonderful in-laws after the divorce.
This user urged OP to protect her money, credit, and accounts from her ex
Is deliberately cooking meals he dislikes harmless comedy, or should everyone stop catering to him without framing it as revenge? And if a marriage ended this way, would keeping the in-laws feel comforting or impossibly complicated?
