Teen Says She Found Proof Her Dad Was Cheating as a Child, Now She Refuses to Speak to Him ” I want Nothing To Do With Him, Ever”

She carried the secret for years: a discovery made as a child that upended how she saw the person she should have been able to trust most. Now a teenager, she has drawn a hard line—refusing to speak to her father and declaring, “I want nothing to do with him, ever.” The rawness of that stance landed her in the r/AITA forum, where the question was simple but devastatingly complex: is cutting off a parent an overreaction, or a necessary boundary born from betrayal?

What the situation looks like

The core of the story is heartbreak, not hearsay. As a child she found proof that her father had cheated, and that discovery shaped her understanding of him and the family. Over time, the knowledge fossilized into anger and distrust. By her teenage years she reached a point where she could not reconcile the person who was supposed to protect her with the person she had evidence of. The result was a categorical refusal to maintain a relationship. That choice has rippled through family dynamics and prompted tough questions from relatives and strangers alike.

Why this feels like more than a broken promise

Infidelity isn’t only about a relationship between two adults; when there are children, it reframes safety and reliability. For this teen, finding proof as a child meant the betrayal was processed during formative years, when trust is being built. Children often interpret parental misconduct as a failure of care or truthfulness about how the family functions. The pain can be compounded if the parent minimized, lied, or continued the behavior. That accumulation of hurt explains why she would reach for finality rather than forgiveness.

Family reactions and the pressure to reconcile

Families rarely respond uniformly to revelations of infidelity. Some relatives prioritize keeping the family unit intact and urge forgiveness or at least a détente. Others side with the child, validating feelings of hurt and anger. The teen’s refusal to speak to her father likely triggered attempts to persuade, guilt trips, or advice to “move on” from various quarters. Those responses can be as alienating as the original betrayal, particularly when they dismiss the child’s emotions or demand a rapid return to normalcy.

Is cutting a parent off ever justified?

There are no universal rules about when it is acceptable to sever contact with a parent. Each case depends on the specifics: whether trust can be rebuilt, whether the parent has taken responsibility, whether ongoing contact is harmful, and how the cutting off affects the teen’s mental health and support network. For many people, permanent estrangement is a last resort after repeated betrayals or sustained abuse. For others, setting an absolute boundary is an act of self-preservation. What feels justified to the person who bore the pain may look extreme to those who are not carrying it.

What the teen—and other young people—can do next

Choosing not to speak to a parent is a heavy emotional stance, and it benefits from practical supports. Therapy can provide a neutral space to process betrayal, weigh options, and develop communication strategies if reconciliation becomes possible. Building a trusted support system of friends, other family members, or mentors helps prevent isolation. If safety is a concern—emotional or physical—it’s important to create a plan and involve professionals or authorities when appropriate. Documentation of incidents, conversations, and feelings can also be useful if legal or custodial questions arise later.

What To Keep In Mind

The most important takeaway is that emotions triggered by betrayal are legitimate and deserve attention. Refusing to speak to an untrustworthy parent is a boundary that can protect mental health, but it should be accompanied by care: seek therapy, rely on supportive people, and be open to revisiting the decision if circumstances change. Families often ask for quick forgiveness, but healing rarely follows a timetable. For parents, acknowledging harm, owning mistakes, and showing consistent effort over time are the only paths toward rebuilding trust. For teens, there is no shame in prioritizing your well-being. If reconciliation ever becomes an option, it should be on terms that feel safe and true to you—not because others demand it.
