Good post. Great to see progress in your relationship with your dad!!! I am very happy for you both!
On a related note, I recently went to the funeral of an inactive JW. There were a number of people about my age (40) who I have known since we were teenagers in the same hall. There were, if I recall 8 of us there roughly the same age, and all baptized. Of the 8, all of us married witnesses. Of the 8 of us who married witnesses, 6 of us divorced our JW mate. Of the 6 who divorced our JW spouses, 5 divorced because the other JW spouse committed adultery. The other one had an affair of her own. The other two who are still married have faded with their spouses.
Its a shame that JWs frown so heavily on marriage counseling and therapy. Think of the families that would still be together if they would learn to understand themselves and work on their marriage.
