Betrayal cuts deepest when it comes from those we hold closest, and for this young woman, that sting came from her own brother. The cruel words he whispered to her fiancé—condoning infidelity and belittling her worth—shattered the fragile trust she had in their bond, leaving her reeling in shock and heartbreak.
Years of enduring his condescension and superiority were finally eclipsed by this devastating breach of loyalty. Her plea for understanding met denial and anger, isolating her further as she grapples with the painful reality that sometimes family can be the source of our deepest wounds.
AITA for cutting off my brother after he told my boyfriend it’s okay to cheat on me?
As noted by Dr. Terri Givens, a social psychologist, familial relationships often involve deeply ingrained power dynamics that can resist change, especially when one member (like an older sibling) has historically occupied a dominant role. Givens emphasizes that maintaining ‘family peace’ often becomes a mechanism for suppressing individual grievances rather than resolving them.
The brother’s actions—encouraging infidelity and making judgmental comments about the OP’s employment and weight—demonstrate a clear lack of respect and a pattern of superiority. When the OP shared this information with her parents, their reaction—focusing on their discomfort (‘awkward’) and pressuring her fiancé for telling her—is a classic example of triangulation and enabling behavior. The parents are prioritizing the perceived comfort of the disruptive sibling over validating the OP’s justified emotional response to a serious breach of trust. This shifts the burden of responsibility onto the victim (the OP) for causing tension.
The OP’s decision to refuse tolerance and consider cutting off contact is an appropriate response to protect her relational boundaries and mental well-being from ongoing toxicity. A constructive path forward would involve clear, firm communication with her parents, stating that their refusal to acknowledge the brother’s harmful conduct is damaging the relationship with them. For the future, she should limit contact with the brother to necessary interactions only, reinforcing that respect and trustworthiness are prerequisites for close family ties.

The original poster is dealing with profound betrayal from a sibling whose behavior has escalated from minor insults to actively encouraging infidelity in her relationship. Her subsequent attempt to seek support from her parents resulted in the conflict being redirected, leaving her feeling isolated as she is now pressured to accept the behavior to maintain family peace.
Should the primary obligation be to maintain familial harmony by overlooking severe boundary violations, or is prioritizing the emotional safety and trust within one’s primary relationship the necessary course of action when a family member actively undermines it?
