The thing that scares me is that the bottom is a pretty realistic depiction of someone who has been horribly emotionally abused for years and years, forced to become completely reliant on their abuser and isolated from the world, etc. Like. The author hits on even less talked about but very real aspects of escaping from and recovering from an abusive relationship.
And yet she... talks like the abuser is a good person? How? How? How? How do you write one of the most realistic effects of a toxic abusive relationship on the victim/survivor and still not realize? Or justify it?
Yeah. I'm waiting until this story ends. I assumed it would end with the bottom getting with the non-abusive character but my expectations have hit rock bottom.
