WIBTA if I (25m) attend the bachelor party of my abusive friend (25m)
We met in college and have been friends since. His now fiancé(23f) told my girlfriend (23f) last year that he has hit her before, but she'd definitely leave if he did it again.
I've recently come to find out he has continued some abuse (im unsure to what degree). I don't agree with this behavior at all and don't want to go to their wedding, but I also don't want to remove any potential lifelines his fiancé could use if she ever leaves. She has already lost some close friends because of this.
I just feel so guilty about having fun at his bachelor party/wedding when I don't agree with this marriage/behavior
