Great Post Stephane ! This is exactly what I decided to do, and stuck to it. My JW family have become distant, and in a small way, they "shun" us, we do not get invited to family JW stuff, like Weddings, and there are children in the family that we have only seen briefly, in a shop or something, and so have never got to know.
They treat us as though we are Disassociated, though we are not officially. I think we are lucky in a way, that their actions are not more harsh.
We are also lucky that most of our close family are out, my kids, and my In laws are all out, and we have grown much closer to family that never was JW. We also have some very good, lovely, real friends that have also never been JW's.
But, you simply have to decide how you are going to handle things, and see how they pan out, when you leave. Personally I do not think a kind of " Theocratic Warfare" is morally wrong, I have been cagey, and economical with the truth, with Elders who were set on getting me DF'd for Apostasy, and I never reveal all I know and feel to my JW family, or any other JW.
I prefer to stay officially "Inactive" , so that if, has happened a few times, JW's that I know who have decided to fade, have no fear of being seen to approach me, and I am able to support them through those early days.
To anyone thinking of leaving I say, DO IT ! but decide which course of action is best for you, and then, be very careful !
