Burn

 Because I'd be the one getting the burn. Not you. 

"If you ever find yourself hurting because of what I did - please, let me go at that moment. Don't ever regret leaving me when you are in pain just as well. I won't be the same person you know now and I won't even know you. I won't remember loving you at all. That's why I'm telling you, when the going gets tough, leave me."

"I won't ever leave you. Why would you think of something like that in the first place? We've been together for almost two decades. How could I even function anymore with a life that has no you in it? I'll weather every storm with you. I'll sit in the dumps with you. Nothing you say or do can make me fall out of this relationship. Because finding you took a lifetime to happen. You won't ever happen again."

Next day
