A weekend of it? I thought we were talking about support groups, not social clubs.
I know a couple social clubs for CD/TG and spouses are always welcome at their meetings and events, but they are not support groups.
A weekly support group just for spouses of CD/TG is hard to find.
Allowing spouses to attend a CD/TG support group is just not the same thing. At least that's what I have heard said by actual spouses.
