I LOVE how Taylor uses music therapy to heal her relationships with her exes, in contrast to other celebs who turn to drugs, alcohol, and acting out. This is a very dark song & video. Who hasn't been there in love? But it's prophetic that she admits she knew—as everyone does—that this guy would be trouble—but she pursued the relationship and the excitement and the intrigue anyway. The message is eerily poetic: you don't know who you are until you lose who you are! My annotation is that the need to find yourself again is what causes you to grow.
