The quote reflects the complicated nature of love and attachment, highlighting the pain of unreciprocated feelings. When you invest emotionally in someone, the loss can leave a lasting emptiness. The experience of being left for someone else creates a burden, as one is left with strong feelings of love that have no outlet, making it difficult to move on. This cycle of love and loss can be quite devastating, as it can repeat with new relationships that might end in a similar way.

In Philip K. Dick's "Flow My Tears, the Policeman Said," love is portrayed as a powerful yet ultimately tragic emotion. The idea that love can remain unfulfilled throughout life emphasizes the deep sense of longing and the inevitability of heartbreak. The longing for connection can persist even when faced with repeated disappointments, suggesting that while love is beautiful, it also carries the risk of profound sorrow and isolation when relationships dissolve.
