The song is a reflection of Winehouse's own struggles with addiction and her tumultuous relationship with Blake Fielder-Civil, whom she married in 2007. In an interview, Winehouse said that the song was about "being with someone who's not good for them, but they can't help but love them."
The song is a powerful ballad that captures the pain and longing of a woman who is in a relationship with a bad man. Winehouse's soulful voice and heartfelt lyrics make the song a memorable and moving experience.
Here are some of the lyrics that illustrate the meaning of the song:
* "I cheated myself, like I knew I would / I told you I was trouble, you know that I'm no good"
* "I never meant to hurt you, I never meant to cause you any sorrow / I never meant to make you cry, I know that I can't take it back now"
* "You knew that I was no good, but you loved me anyway / You're the only one who sees the good in me, the way that I could be"
These lyrics show that the woman in the song is aware of her own flaws and the pain she causes her partner. She also expresses her love for her partner and her regret for hurting him. The song is a bittersweet reflection on a relationship that is both passionate and destructive.
