Not Another Happy Ending

Story about a schizophrenic and vulnerable woman called Jane and her relationship with a manipulative psychopath called Tom.

When Jane was a child her mum died, and her dad turned to booze and disappeared, which seems to have contributed to her pursuing abusive relationships with father figures. Tom wages a campaign to make Jane's life as miserable as possible (resorting to breaking and entering, theft, kidnapping, and threatening to kill her dog), in order to exploit her financially and sexually.

The dark subject matter is hidden in romantic comedy tropes in a similar way to 500 Days of Summer. To begin with it hits every romcom beat - you'll anticipate every new plot point - but gradually becomes less predictable and it's not till the end that it becomes clear if the story's going to be a redemptive one and she either kills Tom or escapes him, with a new sense of confidence, or if it's going to go the full tragic heroine route and have Tom take her away from her remaining family and set her up as a domestic slave. *cough*
