I am so glad you have unconditional love from your mom, who never became a JW. I am so glad your dad is going against 'counsel'/actually against Jehovah's organization. Certainly, he is keeping that a 'secret' in the cong. Have you not been hearing at meetings, from the WT mag., assembly talks with outline from the GB that JWs are not to be talking to any family members DF'd? Won't you just 'cringe' with those talks in the future?
How will you stomach it when you see a mom crying deeply, just hearing her child is DF'd, that now must 'shun' her child? How will you lovingly comfort her? knowing your dad did not shun you. Aren't you aware of the hundreds & thousands of former JWs DF'd now crying, depressed? or do you have some way of dismissing that reality?
8 men in New York will not dictate oh, yes they will. They have been sneaky on you for you to be so naive.
I do hope the best for you to be a loving husband, and in the future, a father with your children, having unconditional love for them also and promising you would never ever 'shun' them, under any circumstances.
