Yes, I would assume if I had a conversation with her siblings about their childhood, the siblings would also talk to my wife about it.

Would it help me deal with the situation if I knew of violence or trauma in her childhood? Mmmmm, I don't know. Right now I am sort of assuming it is there. As I watch this strange and disturbing drama unfold (at the same time that I am a primary actor in the drama), I am trying to figure out why it all happens and childhood difficulty for wifey seems to be the probable cause. Even without physical assault or sexual assault, her childhood was no good. An alcoholic mother, a father who abandoned her.

So I guess that learning whether there was or was not assault or a specific kind of trauma in her childhood is probably a moot point right now.
