Delving into the depths of a complicated relationship, Amy Winehouse paints a poignant picture of unfulfilled love. The song talks about a woman who is emotionally unavailable to her current partner because she is still haunted by her past relationship. Despite his attempts to comfort and pacify her, he can't fill the void left by the man she truly loves. The phrase "he can only hold her for so long" suggests that their relationship is temporary and fragile as she's not completely present with him. It's an exploration of how past relationships can influence our present ones, highlighting the struggle of moving on while still being tethered to what once was.
