emotional terrorism

"... over months and years, living with a person who uses emotional terrorism to obtain what they want can lead to significant frustration and even illness in the recipient. It's like having a fight with an invisible enemy, because the passive-aggressive doesn't use tangible tools. There is no screaming and yelling, no throwing of pots and pans, no name-calling. That is because they need to maintain for themselves their ideal of being perfect." More here.
