MB, first I'd assume you've not been talking with a DB coach who might have a clever idea or two as to how to approach this.
IMHO, the only route I would see if it were me would be to be completely up-front and honest about it. "Do you have doubts about this? I would really like to you see somebody who has been very helpful to me and I think could help us both resolve whether or not to move forward." You'd have to say this counselor is nothing like the other one - apologize if necessary.
I took my W to a counselor who stank - the W had no intention of resolving things - but I think if the counselor was good it might have gotten her to at least consider reconciliation. So I know where you're coming from.
Hopefully a vet will have some sort of similar experience here to help you through.
