I really feel that this song is a love song. The ma. That she loves makes her feel amazing but when she explains being on a rollercoaster they have UPS and downs but fight through it. She explains that he hasn't been loved the right way and she will treat him better than his previous love has. But its not just her feeling she has to love him, but feeling insecure she may not love him right either. She explains "you'll never have to feel that way again" saying her lover doesn't have to feel horrible about there self. "I have broken through" her explaining she broke through his broken heart to make it feel well again. She also says "fighter plane, fly away" saying, do not fight to love anymore, because I promise ill love you right* This song is just beautiful and her voice is just so magical to portray love. I love it.
