This poem is about the heartbreaking realization of holding on to a love that no longer exists. It reflects the pain of not accepting the truth when someone you love tells you they don't want you anymore. Despite knowing the relationship is over, the speaker continues to fight for it, absorbing the pain just to see the other person happy, even if it means breaking their own heart in the process. It's a raw and emotional portrayal of unrequited love and the struggle to let go.
