Betrayal is the breaking or violation of a presumptive social contract, TRUST, or CONFIDENCE that produces moral and psychological conflict within a relationship.
The most immediate effect of the betrayal of trust is in the emotional impact on the person betrayed. Generally speaking, the greater the trust that you had put in the other person and the greater the impact their betrayal has on you, then the greater the distress you will feel. A number of different emotions may be felt upon realizing the betrayal including, most commonly, anger, although there may also be fear and repulsion.
When you are betrayed by someone, it is highly likely that you will not easily trust them again. Trust is fragile and can be lost instantly or there is a period of time whereby a long-earned trust may be eroded and then finally lost.
