Just seeing if what they ask and what they do are complete opposites of each other. Over usage of threats. Constantly asking for things. Using guilt and sympathy to gain control. Blaming you for things that arent your fault. Public humiliation. Passive aggressiveness then denying said passive aggressiveness and playing innocent. Using good moments against you as leverage or as a threat or as a way of "owing".
In short, emotionally manipulative and / or emotionally abusive behavior combined with the denial of said behavior or sudden changes from the bad to the great.
