Robert Pattinson and Kristen Stewart
Unlike Edward Cullen and Bella Swan's forever love, Rob Pattinson and Kristen Stewart couldn't make their relationship last, ending their four-year relationship in May 2013. The main reason for the split? Stewart's shocking cheating scandal in summer 2012 with married Snow White and the Huntsmen director, Rupert Saunders.
