The world needs you, and I wished I could have that with you but I can’t. And I can’t rely on a future version of you that might not be real, you  could  change your mind and I couldn’t live with myself. And I won't make you promise against that. I was too selfish I fucked it all up, and I didn't think, and wasted your time. I'm so sorry.’ He leant forward and his face fell into his hands.
