In the quiet aftermath of betrayal, a young woman grapples with a fractured family torn apart by infidelity. The revelation of her father’s long-term affair not only shattered the fragile trust they once held but also left her mother broken, burdened by grief and financial strain, while the siblings struggled to hold the pieces together.
Amidst this pain, a new life born from deceit stands as a painful reminder of the cruelty that upended their world. Her heart, heavy with anger and resentment, refuses to accept the innocent child as anything but a symbol of the devastation wrought by two selfish souls.
AITAH for hating my baby sibling for being born out of my dad cheating with my mom
Dr. Harriet Lerner, a clinical psychologist known for her work on family systems and boundaries, often emphasizes the critical distinction between holding perpetrators accountable and interacting with innocent consequences of their actions. In this case, the OP is experiencing a natural reaction to severe betrayal trauma.
The core issue here is boundary enforcement and vicarious trauma. The OP’s anger is appropriately aimed at the parents for their infidelity and the subsequent destruction of the family structure, particularly noting the severe, ongoing impact on the mother and the financial burden placed on the brother. Hating the infant, however, is a common, though often emotionally exhausting, defense mechanism where the child becomes a symbolic container for all the rage directed at the parents’ choices. This projection allows the OP to process the injustice because the baby is the tangible, living evidence of the betrayal.
While the OP’s feelings are understandable given the trauma, externalizing the anger onto an unrelated infant is unlikely to resolve the underlying family grief or heal the mother’s distress. A more constructive approach, per relationship experts, involves establishing firm boundaries with the parents—limiting contact, refusing to engage in discussions about the new family—while making a conscious, separate decision about how, or if, to interact with the baby. The recommendation is to focus energy on supporting the mother’s recovery through therapy and separating the parents’ immorality from the child’s innocence to prevent this situation from indefinitely consuming the OP’s own emotional well-being.

The individual is struggling to process the profound and lasting damage caused by their father’s affair, which resulted in significant emotional distress for their mother and the complete restructuring of their family unit. The central conflict lies between the natural anger and resentment directed towards the parents’ selfish actions and the presence of the resulting infant, which the poster feels obligated to reject as a symbol of that betrayal.
If the goal is to protect the mother and maintain family integrity, is rejecting the innocent child the most effective long-term strategy, or does this refusal only prolong the family’s pain? Should the focus remain solely on holding the parents accountable, even if it means permanently severing ties with a new, unrelated member of the extended family?
