My T strongly suspects based on her behavior that my wife is a CSA survivor and is struggling to "keep it asleep" around me now.
I know for a fact she was physically abused... routinely beaten by both parents.
While it's possible that she has some personal CSA issues I wouldn't jump there without some more probing. The physical abuse is significant. Earlier last year when I was reading a number of books on CSA the reactions and behavious described matched my sister exactly. But her abuse was not sexual but physical and emotional. Also bad.
