William & Kate
It seems like ancient history now, but after one too many tabloid pics of William partying with other women in nightclubs, Kate gave William an ultimatum in 2007; and William called the relationship quits! The world was aghast and Kate heartbroken. Nevertheless, within a few months the two were talking again and soon jetting off to the Seychelles to vacation together. Promising to marry at some point in the future, this was a fairy tale ending indeed.
