Regarding “I’m Not in Love” not being a breakup song. I started to agree with you but then if you think about it this poor man’s life has been thrown into despair by the loss of the woman he indirectly and grudgingly now admits to loving. By protesting too much.
If they hadn’t been together and she hadn’t become the memory who brings him to tears then he wouldn’t care so much.
Really artful and quality song. Poetic.
There is a youtube video on the making of I’m not in love that is fascinating. It shows how the creative process came together for that song.
