Cover art for I'm Not Calling You a Liar lyrics by Florence + the Machine

Why does this song not have more comments? It's so beautiful.

To me, the song is about a dysfunctional relationship. The singer is deeply and madly in love, but their partner abuses that (either knowingly or unknowingly). The singer is aware of it, but helpless to get out or stop it.
