Not that I want to. . .

I'm telling you that I have to leave you, but I'm not going until you let me go, because I could never leave you like that, still hanging on. I'll hold you until the tears come. I'll hold you until they stop. I'll hold you until you are strong enough to stand up, and walk away from me. But please, please, don't keep me here too long; You know I cannot stay.
