I understand, truthseeker. What I am suggesting is that you can direct your wife to think about the way she is being treated, and if it is fair? You can do this with gentle questioning.
For instance, is it fair for congregation members to ask after your health? If they really cared, shouldn't they be calling you up themselves? Should she feel obligated to answer their questions? If she were ill and in the hospital, how would she feel if these congregation members were sighing and rolling their eyes behind her back?
Teach her to expect proper behavior, is what I am suggesting.
