What if you thought of out as a friends wedding and a chance to have a blast in a beautiful location? Are you capable of seeing w as a friend for that trip?
I believe in you.
Don't supersize your emotions/reaction to w actions. The real you is a happy fun going man. Remind her of that. Go, and have fun for you. Act as if. I wouldn't even hold up the process she had started.
I'm thinking a 180 would be to return the completed paperwork and go on the trip. Make her a friend and be on your top game. This is a chance for w to see what she will be missing out on. Women don't like weak sad men!
Allow her the opportunity to second guess herself..... Be the confident happy man only a fool would walk away from
