I Blocked My Dad and Cut Off All Contact Because of His Girlfriend and Now Everything Has Exploded
She was 23, he was 49, and the woman he started dating was 21. When the poster on Reddit’s AITAH explained why she blocked her dad and cut off all contact, it read like the kind of family drama that leaves you stunned and furious in equal measure. Her dad had known this girlfriend’s mother since before the girlfriend was born, had stayed in their home while the girlfriend was growing up, and, according to the OP, was effectively part of that family’s life long before he ever showed up consistently in his own children’s lives.
When she confronted him about how unsettling the relationship was, he dismissed her feelings as judgmental and insisted “she’s an adult.” The OP’s boyfriend backed her up. The rest of the family did not.
Exactly what happened, in her words
The OP, who posted under u/softruins, said she tried to talk to her dad about how uncomfortable it made her that he was dating someone barely older than her. The girlfriend is only two years younger than the OP, and the dad had known the girlfriend since before she was born, he used to stay in the house where she grew up. The age difference and the history felt wrong to the OP.
She also carried a deeper wound: her dad is now present and involved in the girlfriend’s child’s life in ways he never was with his own kids. Growing up, she and her brothers saw him maybe three times a year. Now he’s a doting presence in someone else’s life. After multiple attempts to express her distress and being told she was “being judgmental,” the OP decided she couldn’t swallow it and blocked him and informed the family she wanted no part of the situation.
Why this isn’t just awkward, it’s emotional and boundary‑heavy
The post touches three sticky realities: an uncomfortable age dynamic, a history that reads like familiarity morphing into intimacy, and a raw comparison of parental availability. For the OP, the relationship isn’t simply distasteful; it feels like a betrayal. Her anger is compounded by the observation that her father is showing a level of paternal attention to the girlfriend’s child that he never offered to his own. That inequality turned the situation personal, what might otherwise be private adult dating now feels like a public rebuke to everything the OP felt was missing from childhood.
How Reddit reacted: alarm, support, and big accusations
The top comments on the thread skewed strongly in the OP’s favor and used very blunt language. One commenter, u/newdriver2025, wrote simply, “NTA. That is creepy in my opinion,” capturing the instinct many readers had. Several people went further, suggesting grooming: “Part of me wonders if he started to groom her when she was younger,” said u/Thelawtman1986, while u/Zanke95 speculated, “Are we sure the kid isnt his?” Those are allegations rooted in intense suspicion about the timeline of the relationship and his prior proximity to the girlfriend’s family.
Others leaned into the emotional hypocrisy, pointing out that the dad’s current devotion to someone else’s child underscored how absent he had been for his own. A lot of commenters were blunt: “Eww….. It’s giving me really bad vibes… NTA,” wrote u/YJ92boudicca, while u/CelticHipi1680 asked, “How do you know someone as a baby and decide you’re gonig to hit that when they’re an adult. Your dad is the grossest.”
The family fallout: why everyone else thinks she’s the problem
What made the OP feel lonelier was the family’s reaction. Rather than taking her discomfort seriously, relatives told her to “be happy for him” and insisted “love is love.” They accused her of being judgmental and immature and warned she’d regret cutting off her dad. That kind of gaslighting is common in family conflicts where loyalty and embarrassment collide: relatives may defend the parent to avoid acknowledging an uncomfortable truth or because they truly believe adults can date whomever they want without moral judgment. The OP’s boyfriend supported her stance, which highlights how close relationships outside the family can validate feelings the blood family dismisses.
Is cutting off contact the right move?
There’s no tidy moral answer that fits every broken family. From a mental-health perspective, cutting off an emotionally injurious person can be a valid boundary, especially if attempts to explain your limits are brushed off and the dynamic is triggering. The OP said she tried to talk and was dismissed; in that context, stepping away is a protective choice. On the other hand, some commenters pointed out that cutting contact is extreme and irreversible unless the goal is to make a clear, non-negotiable statement. The Reddit consensus leaned toward supporting her boundaries, many top comments marked her NTA, while also voicing alarm about the father’s choices and suggesting the situation warranted deeper scrutiny.
What To Take From This
If you’re watching this unraveling from a distance or living it yourself, there are practical and emotional moves that can help. First, your feelings are valid: discomfort with a parent’s decisions, especially when power dynamics, past familiarity, and unequal parenting are involved, doesn’t make you childish. Second, consider how you want the relationship to look long term. If cutting ties protects your mental health, that boundary can be temporary or permanent; you decide. If you want to keep a relationship, insist on specific boundaries, seek family counseling, or communicate in a written letter that clearly explains your stance without begging for permission to feel hurt.
Third, get support. Find a therapist, a trusted friend, or an advocate who can help you process the comparison pain, watching an absent parent become present for someone else’s child is uniquely wounding. If you have safety concerns or suspect grooming or abuse, document what you know and consult professionals or, if necessary, authorities. Lastly, remember that families often punish the person who points out taboo behavior; that’s painful but not proof you’re wrong. You can choose your boundaries, protect your mental health, and still leave the door open to reassessment if circumstances change. Above all, trust your sense of what makes you safe and sane, and know that many strangers online thought she was NTA for putting herself first.
