Fighting psychological fire with fire is often the most tempting move, but it's not always the best decision long-term. Drawing boundaries with emotionally abusive family members is crucial if you don't plan on cutting them off entirely, but it's best done through a pre-planned confrontation rather than a dinner table screaming match.
Of course, it's far easier to theorize about sitting your family member down for a therapist-approved talk session than it is to actually do it. Plus, there are times when someone needs to be put in their place, and that's the end of the story.
"AITA? My mom called me a wh*re... So I hinted that she’s cheated before, in front of her boyfriend."
"Some back story: My mother has always had this weird anger toward my s*x life. Which, quite frankly.. I believe is not any of her business now that I’ve moved out. She’s called me a slut in the past many times before, made me cry as she called me disgusting, over and over again. You get it. She still seems to always be so curious about it though. Maybe worried, which I understand. But, it never ends well for the both of us. Just conflict."
