Breaking Dawn Theme of Suffering

Pain and love are inextricably connected in Breaking Dawn. Characters suffer because their love isn't returned, they suffer because their loved ones are in pain, and they suffer from feeling too much love for another person. Yet, they all come to realize that feeling love is worth experiencing the pain that comes with it. For example, Jacob maintains his love for Bella until the end of her human life and into her new vampire life. And Bella endures the pain of her pregnancy and her following transformation because she loves her daughter.
