It may be something simple as him being too dependent on his parents and that could be getting in the way of his making progress here or making his own decisions. The therapist might just want him to be more independent, to gain self confidence. It doesn't mean that this is going to be forever.

I agree with the above poster this is too second hand to know whats going on. There is your brothers interpretation, your interpretation and our interpretation...that is a lot of ways for communication to get tangled up.

Then there is the possibility your brother is using the therapist as a scapegoat because he himself wants to cut down communication....too many possibilities.
