Cover art for Rotten lyrics by Naked And Famous, The

The song takes the perspective of a woman whose husband is addicted to gambling (or drugs). She loves him to death, but his lack of self control is destroying their relationship, and it's a pain "he'll never know." She's leaving, and he's desperately trying to keep her from leaving. She forgives him rotten, but she needs to leave, and it's a pain he'll never know.

My Interpretation

@hunter1154 I definitely think drugs—the debt (she probably paid for him) and the “soaking wet cotton” makes me think of shooting dope ????????‍♂️
