Ronan:
Four o'clock in the morning
My mind's filled with a thousand thoughts of you
And how you left without a warning
But looking back I'm sure you tried to talk it through

LeAnn:
Now I see it so clearly
We're together but living separate lives

Ronan:
So wanna tell you I'm sorry
Baby I can't find the words
But if I could, then you know I would, yeah

Chorus
No I won't let go, know what we can be
I won't watch my life, crashing down on me
Guess I had it all, right there before my eyes
Girl, I'm sorry now, you were the last thing on my mind

LeAnn:
You carried me like a river
How far we've come still surprises me

Ronan:
And now I look in the mirror
Staring back is the man
I used to be

With you
How I long for you

Repeat chorus

Ronan:
Girl I'm sorry I was wrong
Could have been there
Should have been so strong
So I'm sorry, wooh

Repeat chorus

I won't watch my life, crashing down on me
Guess I had it all, right there before my eyes
Girl, I'm sorry now, you were the last thing on my mind

Ronan:
Four o'clock in the morning
My mind's filled with a thousand thoughts of you
And how you left without a warning
But looking back I'm sure you tried to talk it through

LeAnn:
Now I see it so clearly
We're together but living separate lives

Ronan:
So wanna tell you I'm sorry
Baby I can't find the words
But if I could, then you know I would, yeah

Chorus
No I won't let go, know what we can be
I won't watch my life, crashing down on me
Guess I had it all, right there before my eyes
Girl, I'm sorry now, you were the last thing on my mind

LeAnn:
You carried me like a river
How far we've come still surprises me

Ronan:
And now I look in the mirror
Staring back is the man
I used to be

How I long for you

Repeat chorus
