This seems to be a pretty common occurence with friends I grew up with. My experience differs from a lot. My dad is an elder and my immediate family are regular. I was DF'd, reinstated, I have been inactive for about 7 years. My relationship is still great with my family even though they know I do not follow the guidelines any longer. My "wordly" fiancee is welcome in their house and we stay over quite often when visiting (in different rooms). Maybe they are more progressive witnesses? I guess I don't know, but I have noticed that stances on certain things depend on the JW. Who knows, if the rest of the congregation knew of the way they treated me, maybe they would be ridculed.
So anyway, my heart goes out to you and anyone who is "shunned" by their family. Unless you don't like them of course, then I guess it's a blessing :)
