There was a letter to an advice column years ago, from a woman convinced her mother in law was slightly poisoning her every time they went to her house for dinner.
After every meal she grew violently ill and threw up/had diarrhea.
When she told her husband her suspicion he said she was crazy. His mother was a saint who adored her and would die before hurting her.
The advice columnist urged the wife to swap her plate with her husband’s during the next dinner. The woman wrote back saying she followed the advice and it was her husband who became violently ill after the meal.
When she told him what she’d done she said he looked at her with such loathing she realized he’d suspected what his mom was doing all along but, instead of standing up for her, he decided to gaslight her about her suspicions to avoid upsetting his mom.
