"half a heart" lyrics

I know you didn't leave, it's not what you do
I see your headlights lighting up my room
Sometimes I just want to run out to show you I've backed down
And let you know that I've been changing too
This is something that I'll never wake up from
Barefoot in the streets, singing love songs
It brings you back to me, brings you back to me

It's hard to love you in the dark
You say, you say that
How can I miss you when you're lost?
When you're lost, when you're lost, when you're lost
I've always loved you from the start
But you've been loving me with half a heart

I heard you were calling my name
It's such a shame to hear it said that way
You don't even mean it anyway
Loose ends, but I think that we can tie them
Cold hearts, but I'm sure that we can find them
And bring you back to me, bring you back to me

It's hard to love you in the dark
You say, you say that
How can I miss you when you're lost?
When you're lost, when you're lost, when you're lost
I've always loved you from the start
But you've been loving me with half a heart

You've been loving me with half a heart
