Sometimes, when you look back on a relationship and its aftermath, it's hard to see how it could have affected you in such a way at that time. I think that's what Tweet is saying... after the smoke has cleared, she has realized that her life is better without that relationship, and even if at one point she cried over him, he is simply "small change" now... That realization, that clarity, is often hard to come by, BUT.... with it comes the knowledge that you can move on.... and a sense of simplicity and peace. I also think that's why the music is so calm and simple... it highlights the serenity she is experiencing.
