Kill me before you leave again.

Everyday I feel a bit of me change with you. You go further away and I reflect the distance, as if on the other side of a mirror. Once free to be anything we wanted, now left with no choice. We will be friends, then. And put this battle to rest. In peace, we will stand, let the fire die out, and walk away from its warmth to our cold embrace. No sun on our faces, no hearts to torch. No ice to melt, no nights to set aflame. No respite, no pain. Only marks on distant stones to reach, no breadcrumbs laid on our paths. I will see you walk away for an eternity, and I know not whether to cry for the infinite distance or settle happily for the infinite beauty forever in view. 
I don't know. I will choose when I have choices again. I will move you when you move into me again. But, love, if you do, you must shatter everything else and be mine forever or kill me before you leave again.
