A ruefull entanglement.
The poem has all the ingredients; Romance, a damsel in distress, long flowing hair, a pain inflicting lass, a rope or maybe a cliff for effect and a tear stained note.

He was living his life blissfully before she entangled him in her charms. With her long flowing hair she cast her net far and wide and when it caught, the embrace was so tight as to cause the poor suggestible lass near suffocation. He experienced fear and arousal in equal measure and could no longer be expected to make a balanced decision on the issue. The dance caused him sleepless nights.
She was finally in her element, a new project so to speak. She had something to throw her attention predatory energy. She approached the acquaintance that fast evolved to a new romance, like one would with a business engagement. Charts, tables, pros and cons. Nothing left to chance. She was now six and twenty and feeling every bit the old maid she could become. All she needed was a fair chance.
He was utterly smitten and no longer in control of his faculties, the lass craved her companionship simply the sight of her; such a delight. He was only too aware of his station in life and often entertained the thought that she was ignorant of the situation with his purse having being cut off from his family inheritance. He often wondered whether it was in his place to inform her, just to clarify but most times he was just glad that his lot in life seemed to be receiving some reprieve.
She was walking on air with pride, glowing with happiness; simply gay. Life could never be kinder. Then matters took a turn for the worse. She got too indulgent and the unthinkable happened. Actually when one thinks more about it, it was rather expected given how she carried on.
A woman her age had few trinkets in her arsenal. She figured she had to be more welcoming and he offered such adventures unheard off she could not resist. He was a gentleman after all she thought. Such harm as was occasioned upon her was unforeseeable according to her.
A whisper from a lady in waiting was all it took. As soon as he heard of her morning ailments, he decided to skip town. Better to do it while he could than wait for the ensuing madness. He had nothing to offer after all.

And so the poem goes that she left her mother a tear stained note and jumped off the cliff that was too willingly availed, to escape her shame.
