This beatifull song is about letting go. When you meat that one person that means everything to you and they just lie to you and they just destroy everything and you love that person so much but they done this to you many times and you just can't afford to forgive them anymore so you're letting go, and at the end of the song when it starts getting slow, they wanted to make it seem like you truly are letting go. And let live agian! Btw Austin said this I'm just posting it here in my own words.
