If we read between the lines, maybe this song really speaks, not of some unfortunate love, but of artistic inspiration and the creative process of writing songs itself. He starts as a love song - I love you and I miss you, but then he gets stuck, what else is there to say. He has no inspiration, it takes far more to complete the song than this supposed, or ordinary love. At night, when the tv subsides, he hears the song in his head and makes changes in keys and meanings. To finish up, the author has many ideas, but they are all a coordinated mess, so well rehearsed, because he is not truly inspired by his love.
