I think recommendations on what to do depend largely upon what she wants at this point.
Is being married to an active JW a marriage worth saving? Is any marriage in this situation worth saving?
I was raised Borg and got married young. Never lived on my own until my divorce in my 40s. Had I known earlier what I know now, I'd have ended the marriage years ago. So I guess one of my points is that this could be a great opportunity.
