I agree.
It is possible to maintain dignity without any drama.
You are behaving as if you desperately want to retain this friendship.
It's over.
For whatever reason she doesn't want to contact you and is happy to humiliate you while you accept it.
It is possible to send a calm, detached message that drops the rope as you step away.

"Message the whole group, saying something like "Despite my repeated attempts to talk to [bride] it is now obvious that I am being ignored for some reason and not welcome at the wedding, so I am leaving this group. Wishing everyone all the best and a happy day.""
This covers it.
You may meet some of the bridesmaids socially and you can be confused about what happened but wish her the best, whatever.
There is a type of person that always has some drama attached to them.
They find offense and upset where none was, or meant.
Stepping away from them is the only action that fully works.
The older you get the quicker you see these qualities in someone and you simply don't get involved at all.
Some people cannot be happy in their life unless their is angst and upset attached.
IMO it is a personality disorder of some type.
I have seen it in both my daughters primary classes, a couple of girls that were constantly in and out of friendships.
My daughters who studiously avoid drama, were the only friends they had that they never fell out with.
They were friends from reception and as they grew, this need for drama grew too.
My girls kept them at a firm distance and wouldn't allow them to be anything other than old casual friends.
The drama continues to this day I believe.
