Missing Piece

I never wanted to beg you to stay,
Or for it to come to this at all,
I wanted to be strong and cold.
But instead I lie in the dark
Scared that if you leave
A part of me will go with you.
But the train went off track
And unfortunately it seems
That there may be no turning back.
I didn’t expect our pieces
To be mixed up and broken,
I thought we would be one.
Now I greatly fear that this piece
Won’t ever return
Leaving me shattered on the floor.
I never wanted to beg you to stay,
But if you go
I want that piece of me back.
