My interpretation goes like this: “Someday, what you did to me will happen to you. Go ahead and blame me for everything if that works for you, if that clears your conscience. When your day comes I’ll be there to see it happen and I take comfort in that fact. So go ahead and finish tearing me down. I know you, I know your deal. And I will be there when you fall. You can’t see the fact that nobody else can take care of you like I can. And when you finally do realize it, when you start to wonder about what we could’ve had, don’t come around. I won’t have anything to do with you.”
