Your love for me, it didn't last long
One part right, and two parts wrong
One part love, two parts pain
One part sunshine, two parts rain

My friends told me you were slippin' away
I smiled and said I don't believe what you say
As long as they'll always be birds in the sky
Your love, your love for me, baby, will never ever die

Oh darlin'...

Your love for me, crumbled in doubt,
One part truth and two parts lie
One part rock and two parts sand
One part stayed and two parts ran
[ Lyrics from: http://www.lyricsmode.com/lyrics/t/tim_mcgraw/one_part_two_part.html ]
When you took one step I take two
I'm tryin' my best to hold onto you
But love can't be love without some give and take
And lovin' you too much was my greatest mistake

Oh darlin'...

Oh the love that's in you is all that I need
But you just give one third to me
And all of your sweetness wouldn't last much longer
And if I had it all I would be much stronger

Oh darlin'...

Your love for me, it didn't last long
One part right, and two parts wrong
One part love, two parts pain
One part sunshine, two parts rain

Oh your love for me, crumbled in doubt,
One part truth and two parts lie
One part rock and two parts sand
One part stayed and, baby, two parts ran
Oh one part stayed, and two parts ran
