Justin learned early on in life that he wanted to be a performer and would stop at nothing until that goal was met.  At eleven he was performing on a television show and at fifteen he had started his music career putting everything else in the world on hold, except her.  Sacrifice was had always been a part of their lives.  When Meredith started her relationship with Justin there had to be sacrifices made, when her career took off there more were made.  Now she's on the top of the world, has the man of her dreams, but isn't so sure that her sacrifices got her what she wanted.
