I would probably collapse. Or beat the hell out of the person. If they were going to reject me, I would hope that it would be before we both blow thousands of dollars on a day that would mean nothing to them.
I would have a breakdown and yell at everyone around me. Then I would realize i shouldn't, but continue to serve a Liftetime Special Movie Event performance to get everyone's pity on my side.
Then I would track him and his w***e (who I assume is a thing) down and seek my revenge.
It wouldn't surrive it. I would kill it.
Now for real: I would scream and shout, insult him with words he never has heard in his life. After
that, when I am on my own I would cry and get drunk or/and high with my besty
I'd just casually walk out and attend the reception so I can get pity and love and then instagram pictures of me in what was meant to be out honeymoon with random people doing things ....
