The most beautiful song on the album. Aside from the implications about Chester's personal life, I think this song is about losing yourself in commitment, and realizing that when it's all over and there's nothing more you can do, you have no choice but to keep going forward.
More elaborately it could further be about still loving someone even though you know the relationship is dead. You love them but you need them out of your life because that's the only way you can be you again. #DeadBySunrise
