You Know I'm No Good

The lyrics describe a relationship damaged by infidelity and mistrust. The speaker admits to cheating, yet still feels attached to her partner and distressed by the pain between them. The mood shifts between swagger and guilt: she jokes about her own bad behavior, but later cries and feels sick with anxiety. Their reunion seems warm at first, then a small clue brings the betrayal back into focus.

Several images make the emotions vivid. “Sniffed me out” suggests that the partner detects her secret as easily as a dog follows a scent. Saying she “cheated myself” implies that her actions also betray her own expectations or hopes, not only her partner. The “little carpet burn” is a physical mark that hints at what happened while she was away; her stomach dropping shows sudden fear and shame. “Who truly stuck the knife in first” compares betrayal to a wound and raises the question of who began the cycle of hurt.

The speaker’s repeated confession sounds both honest and self-protective: she warned her partner she was trouble, but that warning does not undo the harm. It is unclear whether the partner has also been unfaithful, or whether the speaker is simply unsure who first caused the damage. The lyrics leave their relationship unresolved, balancing affection, blame, and regret.
