I default to anger pretty quickly, as well as outrage, one, at them for being despicable,
& two, at myself for not seeing it coming/avoiding it/letting it happen, etc.
I withdraw from them, but not other people, I process better talking about it. In general, I have set up strong barriers over the years to avoid being hurt, because I have had to, I'm very sensitive. So, not much hurts me, nor do people know how to really hurt me. But, when it does happen, I always try to learn from it; I like to understand why/how it happened & thus prevent a similar thing happening in the future, or at least know how to deal with it if it does.
