Indy,
This one slipped under my radar while I was in Germany it seems.
You raise an interesting point, but just to be clear, I'm not sure I would describe how your bf behaves as a result of grooming. "Grooming" is the process by which a pedophile prepares a child for abuse, using lies, gifts and other inducements to make the child feel safe with or dependent upon the abuser. His purpose is to get the child to accept the abuse - when it comes - as part of a relationship that he doesn't want to lose.
So much of what your bf is saying and doing actually reflects pretty exactly the tremendous emotional damage that CSA inflicts on its victims. Every line of what you describe can be traced back to the low self-esteem, lack of confidence, and difficulties with trust that plague so many survivors.
Maybe it would be helpful to repeat something I have said in the past several times in this forum. So many of the hurtful and disrespectful things that survivors do and say do NOT reflect how they really feel about their partners. Rather, these things so often show how distorted the survivor's view of the world has become and how low his opinion of himself is. This is a continuation of all the false lessons abuse taught him years ago.
It's this heap of false lessons, learned DURING abuse, and not the grooming that comes BEFORE abuse, that results in the problems you see before you.
I can't stress enough how experiences early in life can shape our futures. Take trust, for example. A young child will usually trust the world and feel he is safe in it so long as he is with adults he knows. But then one of these people betrays his trust and abuses him. That horrific experience burns into his mind the feeling that no one can be trusted and that catastrophic harm can come to him from any direction at any time. That terrible feeling is false, of course. But trust isn't something we can turn on and off like the lights. It has to be carefully relearned, along with an appreciation of appropriate boundaries. And THAT is a very difficult indeed because the survivor doesn't even trust himself to set out on this task, or anyone else who is prepared to help him.
Hope this helps.
Much love,
Larry
