The refusal isn't any kind of flex. You weren't invited anyway 🤣🤣

So his GF doesn’t like you because of some thing that happened two years ago, and it was so bad that she can’t move forward until you apologize yet no one is going to tell you what your apologizing for? Is it because your parents and bro actually don’t know care about getting the feud over with, or because if you knew you would most definitely not apologize? Or will it turn into an even bigger argument that they don’t wanna deal with? Either way you can’t apologize well knowing what you’re apologizing for. They keep beating around the bush or they can just tell you what the problem is because it starts with the wedding but then what happens at family gatherings, and holidays? On top of them giving you crap for taking away their free wedding exposing them lying to family, wifey is still going to be hung up on the really big issue. She refuses to tell you.

AH worked together, so there is likely some petty shit on both sides.
