Reading things like this makes me doubly happy that I have no jw relatives!
I know for sure that I could never shun my son, no matter what he did, and he's upset me and his mum a few times, to say the least. When I was a jw, I still got along with him, saw him as often as possible, I could never cut myself off from him. If only jws who shun their family members for thinking differrently to them could see what a pathetic, spiteful act it is, but I guess they have to obey the rules, however cruel they are, and their standing at the kh means more to them than family ties.
I think your letter is kind and non-judgmental, and well done for sending both the letter and the card. They should be delighted to receive it, but I doubt they will be. Instead they will, as you say, be saddened, because however good your life is now, you are living outside their religion. I hope they come round one day, but I guess the odds are against it happening anytime soon.
