I say you're stupid, you say I'm stupid, we're all stupid.

I've cried so much over you
I've lied to my heart so much
I believed you over and over again
I was stupid to believe it'd last
I stubbornly believed I could change you
In the end nobody is willing to change
I'm never worth it

All I am is someone to fill in for awhile.

"We're all stupid, stupidly putting forth so much for a love with no future" 
"Hoping for a miracle" 
"We're all stupid, we rather be sacrificed than to give up our naive selves" 
"Who hasn't done something stupid for love?"
