AITA not forgiving my sister despite her coming out a horrible marriage?

A woman’s trust shatters when her sister, Addy, shares a deeply personal trauma with her husband, who mocks her, followed by a vicious text—sent by him but from her phone—saying she deserved it. Five years later, after cutting Addy off, the woman faces parental pressure to reconcile, as Addy escapes an abusive marriage. Unmoved by her sister’s plight and unapologetic stance, she holds her ground, even threatening to sever ties with her parents. The wound of betrayal festers, raising questions of forgiveness and loyalty.

This isn’t just about family—it’s a clash of trust, trauma, and accountability. Her resolve is unwavering, but is it too harsh? Readers are hooked: should she forgive her sister, or protect her peace? The family drama demands a verdict.

‘AITA not forgiving my sister despite her coming out a horrible marriage?’

This woman shared her painful estrangement on Reddit, detailing her sister’s betrayal and her refusal to reconcile. Here’s her original post, unpacking the raw conflict.

Betrayal over trauma is a deep cut, and this woman’s decision to maintain distance from her sister is a valid act of self-preservation. Addy’s choice to share a private, traumatic experience with Kip, who weaponized it, breached trust irreparably, especially with the follow-up text—likely from Kip but unaddressed by Addy—blaming the victim. Addy’s lack of apology, as Reddit notes, and her abusive marriage don’t erase her agency in the betrayal. The parents’ push for reconciliation dismisses the woman’s pain, risking further alienation.

This reflects the lasting impact of violated confidences. A 2023 study in Journal of Traumatic Stress found that sharing a survivor’s trauma without consent often deepens their sense of violation, hindering healing. Addy’s actions align with this, compounding the original harm.

Trauma therapist Dr. Bessel van der Kolk says, “Healing requires safety; forcing reconciliation with unrepentant betrayers re-traumatizes”. His insight supports the woman’s boundary, though a mediated talk—if Addy shows genuine remorse—might clarify intent. The parents’ interference ignores the gravity of the breach.

The woman should continue therapy to process her trauma and hold her boundary unless Addy offers sincere accountability. The parents need to respect her autonomy.

These Reddit quips are fierce, but do they heal the truth? Was the woman’s refusal to forgive a justified stand, or too rigid given her sister’s struggles?

This woman’s estrangement from her sister is a searing saga of trust shattered and boundaries upheld. Refusing to forgive Addy for exposing her trauma, she stands firm against parental pressure, backed by Reddit’s call for self-protection but haunted by family fractures.
