"Tired of Love" is mainly about failure from confusion. As you get older and your baggage and your brain get more cluttered with strangeness and fear, it sometimes feels almost impossible to go along with the simplicity of falling in love, enjoying another person and being kind. This song, for me, was a way of apologizing to someone for not being able to remove myself from all that and be present in the way that I had desired to be for them.
All of that said, whenever I listen to it now, I realize it's a way of me telling that same person how much I care for them, how highly I think of them. By the time it resolves, it's saying "you are amazing, we made this complicated and we can't get what was possible back now.... but I want you to know... you're amazing."
