I have an addiction counsellor and he's helpful. But I never ever say to my partner "He says that I should…." because it doesn't work like that. My addiction counsellor talk things through and I gain clarify each time. But he doesn't dicate action to me.
There are times when I wanted to tell my partner I'd been instructed to do something she doesn't like. But most of the time that's a lie.
And my addiction counsellor and my partner don't meet. Why should they?
