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

Now I see it so clearly
We're together but living separate lives
So, I wanna tell you I'm sorry
Baby, I can't find the words
But, if I could
Then you know I would, yeah,

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, yeah,
Girl I'm sorry now we're the last thing on my mind

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

Now, I look in the mirror (look in the mirror)
Staring back as the man I used to be with you
How I longed for you

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, yeah
Girl, I'm sorry now we're the last thing on my mind

Girl I'm sorry I was wrong
Could've been there, should have been so strong
So, I'm sorry
Oh
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, yeah
Girl I'm sorry now 
(Ooh, I'm sorry) We're the last thing on my mind (on my mind)

I won't watch my life crashing down on me
Guess I had it all right there before my eyes, yeah
Girl I'm sorry now we're the last thing on my mind
(On my mind, on my mind)
