My executioner

You're my executioner, and God alone,
My bliss and my heartache
I'm in heaven when we are back in two
And in hell in the moments of parting.
You're my joy charm.
Being happy is a lifelong pledge,
You and I in whose feet flow,
And who from death is worse than separation.
My life to you I give.
Take it in your lovely hands.
Because you know how much I love you.
It's endless torments.
