A Metal Most Rare

I'll go over the edge because you asked me to.
I'll show you all the pain,
Misery I have stored inside
And the emotions I've deemed weakness.
You can see all this because you care.
You have not just told this to me.
You have shown me,
In what you do.
The way you enjoy my company,
Seek it out,
And share with me your own pains,
How you do not let me believe
That time you spend on me is wasted,
All this
Earns you my trust,
My love,
And poem after poem
As you show me God's love.
So I thank you.
You are a metal
Most rare and precious,
That I would not exchange
For all the world.
