I Thought She Knew

She was my once in a lifetime Happy ending
She was my once in a lifetime 
Happy ending come true 
Oh, I guess I should have told her 
But I thought she knew 
She said I took her for granted 

It's the last thing I would do 
Oh, I'll never understand it 
'Cause I thought she knew 
(I thought she knew) 
I thought she knew my world 
Revolved around her 
My love light burned for her alone 

But she couldn't see the flame 
Only myself to blame 
I should've known, I should've known 
A heartful of words left unspoken 
Now that we're through 
I tell my soul to have the silence broken 
Oh I thought she knew 
I thought she knew my world 

Revolved around her 
My love light burned for her alone 
But she couldn't see the flame 
Only myself to blame 
I should've known, I should've known 
She was my once in a lifetime 
Happy ending come true 
Whoa I guess I should have told her 
But I thought she knew 

I thought she knew 
I thought she knew 
I thought she knew 
I thought that she knew
