Please Leave My Darling Alone

Please leave my darling alone she's the only love I have known
Go find someone else I want her for myself so please leave my darling alone
Down deep she wants to be true but like a child with a toy bright and new
The fascination is there and she might learn to care
Then she'd trade the old for the new
So please leave my darling alone without her I just can't go on
She was never untrue until she met you now please leave my darling alone
