James Blake's song "Are You In Love?" explores the complexities of a romantic relationship and the insecurities that come with it. The lyrics ask if the person he is singing to is truly in love, and if they are, he implores them to show their true feelings. The song suggests that the singer has been putting in a great deal of effort and trying his best to make the relationship work. He wonders if the other person is reciprocating these efforts or if they are truly in love with him. The lyrics also mention a defense mechanism that the singer holds onto, which could be a way to protect himself from getting hurt. However, he questions whether this defense is worth holding onto, indicating a desire for vulnerability and openness in the relationship. There is a sense of uncertainty and insecurity throughout the song, as the singer fears being lied to and wonders if his efforts are in vain. He seems to have experienced past disappointments, as mentioned in the line "No idea of how many lied to me, But the memory survive, survive in me." The repeated phrase "Borrowed time" suggests that the relationship may be on shaky ground and hanging by a thread, with the possibility of it ending at any moment. Overall, "Are You In Love?" delves into the doubts and insecurities that arise in a relationship, and the longing for assurance and reciprocation of love.
