If a partner controls everything within the relationship and tells the victim what to think and believe – so much so that they’re unsure what is and isn’t true any more – this might be a case of perspecticide.
Lisa Aronson Fontes, a psychology researcher at the University of Massachusetts Amherst, told Business Insider: “In an abusive or controlling relationship, over time the dominating partner changes how the victim thinks.
“The abuser defines what love is. The abuser defines what is appropriate in terms of monitoring the partner. The abuser defines what is wrong with the victim, and what she needs to do to change it.”
