Demi and Wilmer began dating in 2010 [3], and are just one of the many pairs who have broken up this year [4]. The couple shared many sweet moments [5] throughout their relationship, and Demi has credited the actor with being a huge source of support [6] throughout her battles with bipolar and eating disorders. The news comes just days after the death of Demi's great-grandmother [7], who passed over the Memorial Day weekend.
