The user, a 28-year-old woman (OP), developed close friendships with her best friend and her best friend’s partner. During this time, the OP secretly developed feelings for the partner because he provided emotional support that the OP lacked, especially while she was enduring a separate, long-term abusive relationship.
Complicating matters, the OP witnessed the best friend mistreating the partner, including admitting to infidelity and physical abuse. After the best friend and the partner broke up, and the OP also left her abusive relationship, the OP and the partner eventually began a relationship, leading to an engagement and pregnancy. The central conflict arises because some observers believe the OP violated a social code by entering a relationship with her best friend’s ex, leading the OP to question if she was wrong in pursuing this connection.

AITA for starting a relationship with my best friends long-term partner after they broke up?












According to Dr. Jules Murphy, a specialist in relationship dynamics, ‘When evaluating ethical breaches in personal relationships, the primary consideration must be the cessation of harm and the establishment of genuine mutual respect, rather than adherence to rigid, context-independent social contracts.’
The OP’s situation involves two distinct ethical layers: her initial feelings and her later actions. While harboring feelings for a friend’s partner is a common internal struggle, the OP did not act on these feelings until both relationships had legitimately ended. Furthermore, the context is crucial: the OP witnessed credible evidence that the best friend was actively abusive and unfaithful to her partner. This observation fundamentally changed the moral calculus; the partner was no longer simply ‘the best friend’s,’ but a man allegedly being mistreated by his partner.
The OP acted on a principle of protecting an individual she saw being harmed, aligning her eventual partnership with a relationship based on mutual care rather than betrayal. The path forward requires the OP and her fiancé to maintain strong boundaries against external judgment and focus on the stability they have built. While navigating friendship fallout is difficult, prioritizing established safety and authentic connection over outdated social rules is generally viewed as the healthier long-term choice.

The OP is currently in a supportive and loving relationship that resulted from a path guided by her need for emotional safety and her observation of her best friend’s mistreatment of her partner. The conflict stems from the tension between her personal happiness and the expectations of loyalty or ‘girl code’ imposed by outside observers regarding relationships with friends’ ex-partners.
The core question for evaluation is whether the OP’s decision to pursue a relationship with her best friend’s ex-partner, whom she knew was being mistreated by her friend, constitutes an unforgivable breach of friendship ethics or a justifiable pursuit of a healthy partnership after witnessing clear evidence of the former relationship’s toxicity.
