Nothing seems more difficult to recover from then when someone whom you have trusted suddenly, and without warning, does something you did not expect that is life altering or affects the safety of your relationship with that person. The shock of the betrayal of trust from someone whom you expect to be trustworthy, whether it be your parents, a friend, a lover, an abusive encounter, whatever the case may be, when trust is broken, something deep inside of us is altered. And at the time, it feels like permanent damage to our souls.
We are internally wired to trust, to believe, to hope for goodness from other human beings with whom we are in relationship with. There is something almost naïve in all of us that assumes that other people will treat us with common courtesy and goodness, loyalty and essentially be trustworthy people in our lives. We were hard wired to trust. Now you may be questioning the truth of these statements as with almost complete certainty, you have at least one, if not two or more stories coming into your mind right now that has proved otherwise that people are genuinely trustworthy. If this is the case, then you have learned the hard lesson through a betrayal that has happened in your life that caused you to challenge this inherent sense of need to trust. The reason for this, is simply this: broken trust has altered you.
Before we experience a trauma of any kind, we expect things to be generally good. After a trauma, our sense of personal safety is now the major focus of our life.
