She was my once in a lifetime
Happy ending come true
Oh, i guess i should have told her
I thought she knew

She said i took her for granted
That's the last thing i would do
Oh, i'll never understand it
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 have known
I should have known

A heart full of words left unspoken
Now that we're through
I'd sell my soul to have this 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 have known
I should have 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
