Finally

It is unhinged for drama but it is the first time I see it addressed in fiction: abusers often accuse others of being the abusive ones, either the victim (tactic called DARVO) u others (the "every accusation is a confession" thing) like priests and anti LGBT lobbysts always harass queer people and drag queens but then they're busted for child abuse and posesion of illegal contents about minors themselves.
I read A LOT (up to 400 books per year) and I don't recall any fiction work that had shown an abuser using these manipulative tactics
