As he watched her walk away, fading quickly in the dark. He fought back a sob, a tear, as he nursed his broken heart. She had made her choice at last and brought an end to their affair. A universe of might- have- beens vanished in that cold night's air. How bleak his future looked right then for she would not dwell there. Triangles are difficult and swans belong in pairs. His children he saw in her eyes now never would be born. He would find another Lover but never Rose without a thorn.
The end of a love triangle. In the denouement she married neither.
