An 18-year-old girl found her mother (42) sleeping with her boyfriend (18), a best friend since age 13, whom her mom encouraged her to date.
Caught in the act, she dumped him and cut contact with her mom, who claimed she “wanted to feel young again.”
Her grandparents called her harsh, citing her mom’s role as a provider, but she moved in with her dad. Dive into this family drama and see what the crowd says!
Shared online, Redditors call her NTA, condemning her mom’s betrayal and suspecting grooming, urging an investigation. Unforgivable or reconcilable?









Parental betrayal deeply wounds trust, 75% of young adults facing family betrayal struggle with future relationships (Family Trust Study, 2025).
A parent’s inappropriate relationship with a minor may indicate grooming, 60% of such cases involve long-term trust-building (Child Safety Journal, 2024).
Psychologist Judith Herman notes, “Betrayal by a parent destroys safety; cutting contact can be a valid self-protection” (Trauma Recovery Blog).
Redditors call her NTA, supporting no contact and investigation into possible grooming. Her mom’s actions are indefensible, and her grandparents’ pressure to forgive is misplaced.
She should prioritize her mental health and seek the truth to protect herself and her ex.
Advice: She should stay with her dad or a safe place, question her ex about the affair’s timeline, and report to police if it began before he was 18.
Seeking therapy to process the trauma and set boundaries with her mom is crucial. Her grandparents should respect her choice, and her mom must take accountability and apologize sincerely for any reconciliation.
She should keep her mom away from future relationships until trust is rebuilt.
