Back At Your Door (Demi Lovato and Cher Lloyd)

Hi my name is Demi Lovato. I just broke up with Cher Lloyd. I found out she cheated on me. Shortly after we broken up. My best friends Nate, who was Cher's younger brother, and Samantha who was Nate's wife. Gotten into a car crash in a very bad storm. They both passed on. Leaving there family, there 3 year old son and myself. Without them in our lives. It was going to be hell on us all. But everything is so confusing. Did Cher really did cheat on me? Did she had something to do with that car crash? I need answers but I'm not sure of how to get them.
