I think the majority of comments have covered the basis of it already but I read somewhere recently, might have been Buzzfeed, that Taylor said it's more about the fact that she'd been in a city where an ex lived for two weeks and hadn't even thought about it and when she did it was just coming to that realization that she was over him, didn't have any urge to call him or anything.
Disclaimer: I can't confirm if it's specifically about anyone as I've heard it's about an ex in particular but also read that everything she writes is factual and more as a coping mechanism for those who need a song to relate to.
