AITA for refusing to attend my little sister’s wedding because of her father assaulting my wife years ago?

An older brother is refusing to attend his much younger half-sister’s wedding because he doesn’t want to be anywhere near the man who once poured an entire bottle of wine over his wife at their engagement party 19 years ago. That incident left his wife humiliated and ruined what was supposed to be a special night.

Now that Vivi is getting married, the family expects him to set aside his long-standing no-contact rule. Mom insists Chase wouldn’t dare cause a scene at his own daughter’s wedding, but the brother stands firm – he holds no grudge against Vivi or their mother, yet he won’t risk having that man near his family again.

‘AITA for refusing to attend my little sister’s wedding because of her father assaulting my wife years ago?’

The complicated family dynamic starts with how the brother views his sister’s father:

Long-running family conflicts often stem from unhealed wounds, and here both sides share some blame for the original incident 19 years ago. Chase pouring wine was clearly unacceptable – physical aggression in any form crosses a line, no matter the provocation.

That said, the revelation that OP’s wife deliberately poked at Chase’s deepest insecurity (being rejected for marriage multiple times) shifts the perspective considerably. Her comment amounted to public emotional bullying at a celebratory event, making Chase’s over-the-top reaction wrong but somewhat understandable in the heat of the moment.

Relationship expert John Gottman identifies contempt as one of the “four horsemen” that destroy connections. OP’s wife showed clear contempt, and Chase responded with violence. Both escalated things, yet neither apparently apologized or made amends afterward.

Today, OP’s choice not to attend directly hurts innocent Vivi. Maintaining no-contact with Chase is his right, but weaponizing it against his sister’s big day risks creating fresh pain. Practical steps forward: talk directly with Vivi about how much he cares, consider attending while minimizing contact with Chase (separate seating, late arrival/early exit), or send heartfelt gifts and wishes without showing up if it’s truly impossible. Open, honest communication with his sister – not through their mom – matters most.

The crowd quickly flipped after OP clarified in comments that his wife had provoked Chase by mocking his failed proposals:

Nineteen years later, old wounds still shape family ties, and one buried detail changed everything for most readers. Vivi remains caught in the middle of choices that weren’t hers.

These stories always spark debate about forgiveness, loyalty, and consequences. Where would you draw the line – protecting your spouse’s feelings no matter what, or showing up for an innocent sibling’s milestone? Would knowing the full provocation change how you’d handle a similar grudge today?
