Where do broken hearts go?

"Counted all my mistakes and there's only one
Standing out from the list of the things I've done
All the rest of my crimes don't come close
To the look on your face when I let you go

So I built you a house from a broken home
And I wrote you a song with the words you spoke

Yeah, it took me some time, but I figured out
How to fix up a heart that I let down

Now I'm searching every lonely place
Every corner calling out your name
Tryna find you, but I just don't know
Where do broken hearts go?"
