Promises Don't Come Easy
I should have known all along
There was something wrong
I just never read between the lines
Then I woke up one day
And found you on your way
Leaving nothing but my heart behind
What can I do to make it up to you
Promises don't come easy
But tell me if there's a way
To bring you back home to stay
Well I'd promise anything to you
I've been walkin' around
With my head hanging down
Wonderin' what I'm gonna do
'Cause when you walked out that door
I knew I needed you more
Than to take a chance on losing you
What can I do to make it up to you
Promises don't come easy
But tell me if there's a way
To bring you back home to stay
Well I'd promise anything to you
You never thought I loved you
I guess you never thought I cared
Well I was just too proud to say it out loud
Now I know to let my feelings go
(So tell me)
What can I do to make it up to you
Promises don't come easy
You know I've made up my mind
To make it work this time
That's the promise I can give to you
What can I do to make it up to you
