I DA'd in sept. 2008. I don't have any family in so it was easier so to speak, to write a letter and end my relationship with an organization. I think if I had family in it would be real hard to leave. Your raised thinking family is more important than anything and to lose them because you disagree with false teachings is something very hard to deal with. I feel sorry for those on here who have family in. But I understand why they stay. I could never judge them for staying because of that, especially since I haven't walked that road. You have to make a choice for yourself. Everyone is different and if you stay for family than do that.
If you choose to leave be prepare to lose every close friend you have. They turn their backs on you real fast. Some have been lucky and had some keep talking to them but for the most part they will all shun you. I have a daughter and it was hard to tell her I was leaving the JW's and she would lose her best friend. It crushed her, but we talk about it and I try to help her see that what mom was teaching her wasn't right. She tells me now that she only went to the meetings because of her best friend, it was pretty boring for her.
I hope you make the right decision for you and your situation.
