shouldve said no

The speaker has learned that her partner was unfaithful, and the trust and happiness they once shared now feel lost. Although the partner says it was a moment of weakness and asks for another chance, she is hurt and doubtful. Her feelings move from shock and sadness toward anger and a firm sense that the choice had consequences.

The repeated phrase “you should’ve said no” means the partner could have refused the situation and avoided betraying her. “The word … would get back to me” suggests that news of the affair was bound to reach her. The line about being “in the back of your mind” expresses her belief that the partner should have remembered their relationship before acting. “Begging for forgiveness at my feet” presents the partner as pleading, while the speaker holds the power to decide whether to forgive.

The question “Was it worth it?” asks whether the brief experience was worth the damage to their relationship; it is not simply a request for information. The speaker sounds convinced that things cannot return to how they were, but the repeated “might still have me” leaves a small ambiguity: perhaps the relationship could have survived if the partner had made a different choice. The lyrics do not say whether she will ultimately forgive or leave.
