You were supposed to be mine...

Yesterday I was so happy and full of delight,
Tomorrow I'll be all alone in the night...
Yesterday's girl is all I'll be,
I'll be nothing but a memory...
Back to the life you say you must go,
A mask I shall wear so my pain will not show...
My heart says you love me and with me you'll stay,
My mind knows the stakes are too high,
A price you can't pay...

Our love will be lost as if from a roll of the dice,
To keep my dreams safe I'd pay any price...
There's a pain in my heart, you're not even gone,
Suddenly I feel sick inside... I don't know how to be alone...
My heart is bleeding, I'm so full of pain,
I knew the deal from the start, I have no one to blame.
My broken heart will mend, it's gonna take some time,
I don't know why it's not so...
You were supposed to be mine.........
