Main character's Problem

Adam, Mia's ex-boyfriend, in "Where She Went" faces many problems. In this book Adam is facing depression over Mia leaving him. He does not sleep, he is unkempt, he has bad anxiety, and he gets worked up very easily. He loved Mia and her loss is too much to handle for him at this time. He is a famous rock star but he hates his life. He cannot even enjoy his fame and fortune because of the burden Mia has left on his life by leaving. She didn't give him an explanation and that is weighing very heavily on him. His current girlfriend Bree is perfect. Any guy would dream of having her, but not Adam. To Adam, Mia is perfect and she is the only one that can satisfy him. Adam could easily just move on  and marry Bree but he is still in love with Mia and he always will be. Hopefully they find their way back to each other to make the hurt go away and to be happy again.
