Sharing space with shadows

This room may hold no evil,
This space may be pristine,
But the door to it is locked
And I feel the barrier between.
How can I guess what’s behind your eyes?
I cannot doubt your beautiful mind.
But there is something left secret,
An ominous shadow undefined.
I accuse you of no sin, my love.
You are an angel to me, always.
But when I reach to hold you,
This space gets in the way.
I see only the shadows;
What casts them is off limits to me.
It is their concealment that hurts, so,
More than whatever they could be.
