The song "Darling, You Know I Wouldn't Lie" is not by Elvis Costello and The Attractions, but rather by Conway Twitty. The lyrics tell the story of a person who has been unfaithful to their partner. The protagonist confesses to their lover that they had been seeing someone else, but claims that it was only a temporary infatuation or fascination. They assure their partner that this time it's truly over and that they wouldn't lie about it. The protagonist describes how they had to gently break up with the other person, taking their feelings into consideration. However, it took longer than expected for the other person to understand that the relationship is truly over. The other person's desperate attempts to hold on to the protagonist are evident through the use of lipstick marks and tears on their shoulder. Overall, the song portrays a confession of infidelity and reassurance to the betrayed lover that the affair is now over. The protagonist is expressing remorse and asking for forgiveness while trying to convince their partner that they wouldn't lie about their feelings.
