My son was also DF'ed and I never shunned him, ever! I even told his dad if he wanted to refuse his own flesh and blood into our house HE could pack his bags and leave because that is my son and he stays! Good grief he was barely able to be on his own and his dad wanted to take the hard line, no way 'jose not in my house!
Once my Mother (die-hard Dub) was at our house visiting when my son came home, he didn't see his Grandmother right away and just started eating something. She saw him in the kitchen and came and got me all worried about greeting him. I laughed and said "he's your Grandson not Satan the Devil, go give him a hug everyone can use a hug." Oh man she about peed her pants! That was the last time she came over without clearing it first that he wouldn't be there.......I got sick of her doing that and told her my son is always welcomed in my home and if she had a problem with seeing him there we had best always go to her house there she can control who comes in and who doesn't.
Honestly my son being DF'ed was the best thing that happened to our family, it opened all of our eyes to the hateful ways of the WTS. We are all out except for my Mom and his Dad and a few distant relatives.
I hope time mends the rift in your family it did in ours now nearly 12 years later they quit expecting my son to ever be a part of the WTS again. Now I just wish they would give up on me!
