Amy Winehouse's soulful ballad is a testament to her unwavering loyalty and commitment. The song paints a picture of a woman standing by her partner, ready to support him as he battles his personal demons, which could be anything from addiction to mental health issues. She uses the metaphor of an 'unholy war' to depict the internal struggles that are tearing him apart. Despite the pain and suffering, she is willing to fight alongside him, even if it leads to her own downfall. This song serves as a poignant reminder of Winehouse's own battles with substance abuse and how love can sometimes lead us into destructive paths.
