Misleading

I gave you all I have
My heart was shattered by one
This can never be undone
A puzzle with the wrong pieces
A lock with a broken key
I thought that we were meant to be
But now I can clearly see
My mind has played games with me
Three words that sounded so sweet
I love you
Is corrupt and deceit
It is a lie born from your lips
Ruby lips that kiss with honeyed words
Where fact it's a snake bite with bitter poison
Running through my veins
Killing me slowly and bringing me down
Its our end or mine
A choice a loath to make
But one I have to for my own sake
