what rules my heart lyrics

I hate so say the feelin's gone
But I just can't keep holding on
I hope that's somethin' your heart will allow
I didn't mean to do it
I should have known from the start
I just couldn't put you through it
Sometimes I just don't know
CHORUS:
What rules my heart
What rules my heart
What rules my heart
What rules my heart
Mistreating you was such a crime
I know the hurt will heal in time
But that's a small consolation right now
I didn't mean to do it
I should have known from the very start
I just couldn't put you throught it
Sometimes I just don't know
CHORUS
I just don't know what rules my heart
I never ever wanted to tear us apart
