He Once said to her

He once said to her she was his everything only for her to realise she was nothing. He pretended to care, but never truly did. He once said to her she was the only one only for her to discover there were more than one. He once said to her, till death do us part. But instead of keeping her whole, he is tearing her apart. He once said to her he would be her source of comfort, her joy, her happiness. But why is he now her deepest source of pain? He once promised her heaven and earth. But now, she is rotting in hell.
