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

Last thing I would do

Oh I'll never understand it

'cause I thought she knew

I thought she knew

My world revolved around her

My love light burns 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

I thought she knew

My world revolved around her

My love light burns 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

Oh 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 she knew

I thought she knew

Whoa...

Oh I thought that she knew

Yeah oooooooo...
