Lyrics of My heart has a mind of its own

I told this heart of mine our love could never be,
But then i hear your voice, and something stirs inside of me
Somehow i can't dismiss the memory of your kiss,
Guess my heart has a mind of its own
No matter what i do, no matter what i say
No matter how i try, i just can't turn the other way
When i'm with someone new, i always think of you,
Guess my heart has a mind of its own
You're not in love with me, so why can't i forget?
I'm just your "used-to-be"; it's wrong, and yet...
I know forgetting you would be a hopeless thing,
For i'm a puppet and i just can't seem to break the string
I say "i'll let you go," but then my heart says "no"
Guess my heart has a mine of its own
Guess my heart has a mind of its own
