I don't know how much help it would be, but you might try to organize your group by calling some of the therapists in your area and see if they have clients or spouses who would be interested.
The local crises lines may have a lead or two, as well.
And if you PM our Ken Singer, who helps folks locate local therapists because of his network connections, he may have a suggestion or two.
Good Luck...come back and keep us informed so that others, who may be looking for the same thing, will see what you're doing and where.
