You might want to touch base with the counselor again, about what she can say and can't. You are one of 2 parents, and should be informed of her professional opinion as to the state of the childrens' minds and well-being, as well as informed/educated on how best to mitigate any detrimental effects they are having. She can refer you to another C, just for you, if she feels that it is warranted and would help you in helping and dealing with the kids.

She might not be able to tell you specifically what they talked about (who they are angry at at the moment, for example), but you should be told about their overall mental health.
