I completely understand why some people won't like this song, but at the end of the day she is a songwriter. She is going to be inspired by major life events whether they are her own or of those close to her. She didn't call him out by name; no rules were broken. Yeah it's safe to assume it's about him, but at least it was written it in a way that anyone could apply the lyrics to their own situation. Same goes for Nick. Actually he mentioned her in a verse a few months back, which went under the radar lol. Him favoriting nasty tweets about her isn't a good look though.
