I have enjoyed your posts oompa,
You've recieved lots of opinions on this so I may overlap some of what's already been said but I thought I'd put my spin on it. This thearpist doesn't understand that going to a JW meeting is NOT like going to a mainstream church service. Main stream churches do not use services to control an individual the way cults do.
I am an atheist but I went to a Baptist church with my then girlfriend (now wife) to make her happy early in our relationship but I felt no guilt or pressure from the services and the church expected nothing from me so a main stream church service is, at worst, just a waste of time. You well know JW meetings are far more intense and the foundations of guilt, mind control/independant thinking is BAD, Obey the FDS, type cult control are constant and the congregation will always expect more from you just because you are there.
Meetings are always a stepping stone to more activity in the cult. In my opinion, you cannot remain a passive meeting goer in the Watch Tower system simply because it is not tolerated the same way you can easily remain a passive mainstream church goer for years and years.
Do not go back to the meetings since it is so difficult to leave the cult in the first place. You will have recovery issues for years as it is and meetings will only make this worse. If you explain this to your therapist and they still think it is a reasonable concesssion to your wife I too would recommend a new therapist. Going to a Kingdom Hall is NOT like going to a mainstream church to make your wife happy as they are totally different things. It should be clear that one of the reasons you are in therapy is because of your cult involvement to begin with and you don't need any more abuse from the Watch Tower Society in the form of their brain washing meetings. It is not healthy. It would be just like an alcoholic being told that they should drink socially with their wife if it makes her happy. This is a clear case where your mental health needs to trump her "happiness" which is false anyway since she is clearly a cult victim also.
Best of Luck to you
