I'm of two minds. One, you're still processing how to detach from him -- you bounce back and forth on a daily basis. So if you do bring it up, be prepared for him to pull way back.
Also, who knows what he has been saying to the MC at the sessions by himself. I would almost wait for a joint counseling session before doing that.
Have the MC make the request in front of both of you, so it doesn't come across as pursuing.
