Lyrics:

(Skip Ewing/Keith Urban/Matt Rollings)

I thought You knew, guess I assumed too much
I don't know how but now we're so far out of touch
And I never planned, To so misunderstand
But what you needed you never asked me to give
And I swear as I live...

(Chorus)
I thought you knew my heart was yours
And that we were so together
That we would always be
I don't believe you leaving me's the answer
I'm not asking you to let me rush back in and fail again
I'm asking for one chance not to assume
So I can say and do
All the things I thought you knew

So here we are
And so far we're still so far
From where we know we should be
I'm searching for words
And you haven't heard

(Chorus)
I thought you knew my heart was yours
And that we were so together
That we would always be
I don't believe you leaving me's the answer
I'm not asking you to let me rush back in and fail again
I'm asking for one chance not to assume
So I can say and do
All the things I thought you knew

I thought you knew

Oh God I thought you knew
