Betrayal Trauma

 This is sort of the thing that happens when you put your trust in someone, then discover their actual motives...

Betrayal Trauma: The phrase "betrayal trauma" can be used to refer to a kind of trauma independent of the reaction to the trauma. From Freyd (2008): Betrayal trauma occurs when the people or institutions on which a person depends for survival signifi cantly violate that person ’ s trust or well - being: Childhood physical, emotional, or sexual abuse perpetrated by a caregiver are examples of betrayal trauma. 

Betrayal Trauma Theory: From Sivers, Schooler, & Freyd (2002): A theory that predicts that the degree to which a negative event represents a betrayal by a trusted needed other will influence the way in which that events is processed and remembered.
