Welcome sister

I would explain exactly what you did here to your t. Ask him to refer you to another therapist for the couples therapy. He should have no problems doing that.

Just explain that while you agree with the idea of couples therapy, you still need to have a private session and trust him for that.

Personally, I would NOT want to have the same therapist for individual and couples therapy. I really wouldn't.

Good luck and let us know?
