Gaslighting

http://psych-your-mind.blogspot.com/2012/04/call-me-crazy-subtle-power-of.html A classic example of psychological gaslighting is the following: Spouse A has an extramarital affair and tries to cover it up. Spouse B finds a suspicious text message in A's phone and expresses concern to A. A then accuses B of being paranoid, and this pattern repeats every time B raises concerns. Eventually B begins to question his or her own perceptions.
