[Verse]C Fm
She was my once in a lifetime
C Fm
Happy ending come true
Bm E Em Am
Oh, I guess I should have told her
F G
I thought she knew
C Fm
She said I took her for granted
C Fm
That's the last thing I would do
Bm E Em Am
Oh, I'll never understand it
Fm G
I thought she knew
[Chorus] F Em
I thought she knew my world revolved around her
Am F Em
My love light burned for her alone
E Am
But she couldn't see the flame, only myself to blame
Bb F G
I should've known, I should've known
[Verse]C Fm
A heart full of words left unspoken
C Fm
Now that we're through
Bm E Em Am
I tell my soul to have this side less broken
F G
I thought she knew
I thought she knew
[Chorus] F Em
I thought she knew my world revolved around her
Am F Em
My love light burned for her alone
E Am
But she couldn't see the flame, only myself to blame
Bb F G
I should've known, I should've known
[Outro]C Fm
She was my once in a lifetime
C Fm
Happy ending come true
Bm E Em Am
Oh, I guess I should've told her
F G
(But I) I thought she knew, I thought she knew, I thought she knew
I thought that she knew...
