How Long

Charlie Puth's 'How Long' is a song that delves into the themes of infidelity, guilt, and the quest for forgiveness. The lyrics portray a conversation between two lovers, where one is confronting the other about a suspected affair. Puth's smooth vocal delivery, combined with a catchy pop melody, masks the serious and painful subject matter with an upbeat tempo, a common technique in pop music to juxtapose the mood of the music with the gravity of the lyrics.

The song opens with an admission of wrongdoing from the protagonist, who is trying to separate his actions from his feelings, suggesting that while he may have been physically unfaithful, his heart remains with his partner. The repeated questions from the other party, 'Was it real or just for show?' and 'How long has this been goin' on?' reflect a deep sense of betrayal and the need for truth. The insistence on knowing the duration of the affair indicates that the emotional impact may be contingent on whether this was a one-time mistake or an ongoing deception.
