DARVO style of gaslighting is way too common in society (USA).
Deny
Accuse
Reverse
Victim
Offender
The person denies that their actions caused you harm.
They then accuse you of harming them by making the claim OR claim that the behavior they did was actually you doing it (often despite you having visible proof that they did it.)
They then declare themself the victim of your behavior and thus they do not need to be held accountable, only you do.
It's insidious. And it's nasty gaslighting.
