Working,
My husband is like that when I tell him the gory details of my traumas. He grew up in a 'perfect household' where there was no violence, drinking, abuse of any kind. When I tell him things that happened to me, his skin crawls and it's hard for him to believe that humans can be that cruel to one another. My experiences are so alien to him that he can't wrap his mind around my stories.
He tries to be understanding, though. He gets silent and freezes when I tell him details.
