I hope this isn't true (Poem)

Every good left in me points to you
I promise to carry you in every action I do
I don’t care about the sins you think you carry
You were always mine to bury
I see you in the leftover grey from power-washed concrete
I see you in every dirty cigarette-smoke-scented backseat
You bought it secondhand
A metallic taste like a wedding band
Loving you was every war I have ever won
It was like staring down the barrel of a shotgun
I think when I grow empty and sad
I’ll think of you and scribble the thought down on a notepad
Sometimes when I think of you, I can feel it underneath my ribs
It reminds me of when you looked at her, you whispered it “dibs”
I felt my hollow chest heart get crushed
Your grabby hands going towards her, it was all rushed
I think I was jealous, or at least a part of me
I wanted you like you were a ship and I was the black sea
I knew it was wrong, but at least you would want me, not just my spare time
So I’ll swallow down this hard truth, like a soda and lime
You’ll always age like fine wine
But you will never be mine
