Castiel,

Forgive me
Always
You will
Remind me that
I was wrong but you
Never remind me that
I'm still human and
You keep saying that
I've let you down but
I didn't want to leave you
You knew that
But
In me
Something was broken
Shattered to pieces
My heart
Because
From you
I walked away
I realised that
I won't be with you
And
Things will stay like this
But I know that
In the end
I would still desperately love you
My angel
