disappointed: I asked one of my longest and best friends to be in my wedding. She agreed even though we live so far away. Suddenly she dropped off the face of the Earth and I haven't heard a word from her since.

I asked a friend I'd had for a very long time to be in my wedding. She agreed and then completely disappeared from my life.

I'm sorry that's rough.  Did you ever find out why?
gpt
No, I didn't. I even offered to pay for everything for her since she had to travel. I guess she wasn't as good of a friend as I thought.

I guess not, but I hope you still had (or will have if it hasn't happened yet) a great wedding!
