"What You Gonna Do About Me" by Buddy Guy is a song about a relationship that is coming to an end. The narrator's partner wants to move on and believes that the passion they once had has faded away. However, the narrator senses some hesitation in their partner's decision to leave. The song encourages the partner to think about the consequences of their actions and to reflect on what they will do without the narrator in their life. Despite the difficulties they have faced in the relationship, taking the easy way out and leaving might not ultimately bring the satisfaction the partner is seeking. The narrator suggests that even if their partner finds someone else, they will still be searching for something more, indicating that they may not find the happiness they desire. Throughout the song, the narrator emphasizes that their presence will continue to linger in the partner's mind, even if they try to forget or move on. The lyrics imply that the partner may regret their decision and recognize the value of what they had. The song advises the partner to consider their choices before leaving everything behind and to understand that the narrator will always be there, waiting if they change their mind. Ultimately, "What You Gonna Do About Me" explores the lingering presence and impact of a past love and challenges the listener to consider the consequences of their decisions in relationships.
