Thanks for all the responses, Guys.
My mind of course was telling me all these things you said are true, but Little John would have none of it. He was suddenly very hurt that mom and dad couldn't even protect him from the "obvious" when so much worse had been going on for so many years already. It led him to believe even more in his guilt and complicity in the abuse as though he really did deserve it.
Your responses have served to help him know and feel secure in the fact that it was not his fault and that he no longer needed to feel dirty and humiliated. It also reinforced in his mind that his folks were indeed quite ignorant in the ways of sexual abuse, grooming, all the rest. I remember they thought it was cute and smiled, even chuckled. Little John knew what it was because he'd been around it for 5 years already. They, on the other hand were ignorant of the issues and blind to what was really happening.
Unfortunately Little John was wiser than his parents in this situation yet he had no tools with which to work that could make any difference in his situation whatsoever, and he knew it. It hurts to say that, but they were and he did.
Love you guys,
