AITA for ruining my future SIL’s wedding to be?
OP (30M) received a wedding invitation to his brother’s July 2022 wedding but was the only sibling denied a +1, excluding his boyfriend of two years. When confronted, his future sister-in-law (SIL) admitted she left out OP’s boyfriend to avoid issues with her homophobic family and OP’s mother, later warning that their presence would “ruin” her wedding. Though she relented and offered a +1, her harsh texts left OP questioning if he was wrong to push back.
Social media users supported OP, condemning SIL for enabling homophobia and acting behind the groom’s back. Was OP wrong to demand equal treatment, or is SIL dodging accountability? This story sparks discussion about confronting prejudice and maintaining fairness in family events.

OP’s edits on terminology and plans:



OP’s insistence on bringing his boyfriend to his brother’s wedding was entirely justified, as excluding his partner based on homophobic prejudices is discriminatory. His SIL’s decision to omit the +1 to appease her and OP’s homophobic families, while hiding this from the groom, was unfair and deceptive. Social psychologist Dr. Susan Fiske notes, “Avoiding conflict by excluding groups based on prejudice only perpetuates injustice” (Princeton University). SIL’s actions prioritize the comfort of bigoted family members over OP’s right to equal treatment.
OP’s conflict about potentially “ruining” the wedding is understandable but misplaced. SIL created this situation by making a unilateral decision and then blaming OP for seeking fairness. Family therapist Dr. John Gottman emphasizes, “Honesty and respect are the foundation of healthy family relationships, even in extended families” (The Gottman Institute). SIL’s warning that OP’s presence with his boyfriend would “ruin” her wedding is a manipulative tactic to guilt him into accepting discrimination.
OP should proceed with bringing his boyfriend but prepare for potential negative comments from SIL’s family or his mother. Sharing SIL’s texts with his brother is crucial for transparency, as his brother deserves to know about his fiancée’s actions. If the environment feels unsafe, OP and his boyfriend could consider not attending, but only after discussing with his brother. Support from friends or a counselor can help OP navigate this prejudice confidently.
SIL needs to recognize that enabling bigotry doesn’t resolve conflict but harms loved ones. OP should take pride in standing up for himself and his boyfriend, and his brother should ensure the wedding is a safe, inclusive space for all guests. Equality and respect should not be sacrificed for the comfort of those with prejudiced views.
