I ask this question because I was askedthis question today. And all I could really say is "I close off."
But something else really does happen--- I begin to use that betrayal as confirmation for me to not trust others easily and to keep my fortress strong. I don't hold any grudges on the person but I begin to see how it was I who allowed this person to affect me in such a way that I have to close off.
So me in particular or some sort of MBTI character traits we share at varying degrees?
