As an AI language model, I cannot provide a definitive answer to this question as I do not have enough context about your cousin's behavior or the dynamics of her relationship with her boyfriend. However, the term "simp" usually refers to someone who excessively praises or flatters their romantic partner, often to the point of sacrificing their own interests or dignity. It is possible that your cousin is displaying such behavior because she is deeply committed to her boyfriend or has a low sense of self-worth. It is important to approach this situation with empathy and avoid judging or shaming your cousin for her actions.
