where it shows this girl getting ready to go to a wedding and when her ex turns up at the wedding too, he gives her a look that said "I shouldn't have dumped her" (and it ends with something along the lines of The look on your ex: Priceless)?
That's just happened to me.
My ex has just won two tickets to see England take on Sweden on June 20th with flights and accommodation all paid for.
And I only dumped her a month ago.
