AITA for banning MIL from my life after she said I slept w/FIL?’

In a whirlwind of family drama, a young woman drew a hard line against her boyfriend’s mother, whose venomous lies turned a car loan into a personal attack. The OP, a supportive partner to her autistic boyfriend, faced accusations of infidelity with his father, hurled by a MIL jealous of her son’s newfound independence.

This Reddit saga unravels a tale of betrayal and boundaries, where love for a partner clashes with toxic in-laws. Was the OP right to shut the door on her MIL, or should she mend fences for family’s sake?

‘AITA for banning MIL from my life after she said I slept w/FIL?’

Family ties can fray when jealousy sparks cruel accusations, as the OP learned when her MIL lashed out. The MIL’s outburst, falsely claiming the OP slept with her husband, wasn’t just a personal attack—it wounded her autistic son, revealing a deeper need for control. The OP’s choice to go no-contact protects her mental health, while the MIL’s family defends her as a “good mom” despite the harm.

Psychologist Dr. Susan Forward, author of Toxic Parents, notes, “Cutting off toxic family members is a valid choice when their behavior undermines your well-being.” The MIL’s accusations reflect a pattern of undermining her son’s autonomy, a common issue in families of neurodivergent adults, with 65% of autistic individuals reporting overbearing parental control in studies.

This highlights a broader issue: navigating toxic in-laws while supporting a partner. The OP could maintain firm boundaries, like limiting MIL visits to neutral spaces, and discuss with her boyfriend how to handle future contact. Therapy, already started, can help them process this.
