Hi Chelys
Sorry to hear about your situation. I think your fiancé is being pulled back onto the treadmill by 3 factors : his sickness (which has brought to bear his mortality), recent world events (that seem to have jolted many inactive J.W. back to towing the line - you see they still believe it to be the TRUTH and therefore see the end in sight each time there is a substantial world event) and finally by his devout mom.
Hard to say how this will work out. Are you prepared to wait ? Life goes by so quickly. Even if he pulls back do you want to live with this JW baggage.
