Posted this as a response on another thread, but I know there are people who want this as a new discussion. So...
____________________
I'm sure there are many good people watching these discussions who know you want to leave, but also know that this is what may await you - family alienation and pain.
If you haven't already overtly left, my advice to you is this: don't succumb to the disfellowshipping process . Avoid it in any way you can. Read that again: avoid it in any way you can. Remove yourself from the self-appointed judicial authority of Jehovah's Witnesses.
In that way your family doesn't feel obliged to ignore you. Unless they are seriously hardcore, after time you will just become the wordly son/daughter/relative, but you'll still be able to (1) love them as hard as you can, (2) spend quality time with them, and perhaps even (3) subtly open their minds to what they're caught up in. (The third option is unlikely though!)
How to avoid the DF process?
Firstly, don't do anything, for now, that is a black-and-white disfellowshipping offence. Now is not the time to take up smoking or to set up home with the partner to whom you aren't married, or to appear in the newspaper as Santa Claus at your local mall.
But the following things are not DF offences: not attending meetings, not doing field service, spending time with non-JW friends, getting a good education, moving away from your home congregation, getting a good job, joining sports clubs, developing countless interests that aren't related to religion. The list is long. (Maybe that's another thread.)
Put a bit of time and space between yourself and the JW judiciary system.
Carry on loving your family and being a brilliant son/daughter/parent/aunt...
There is a rule, unwritten I believe, though I haven't read the elders' manual so I can't be sure, that if someone is not considered by their community as a JW for 5 years or so then they fall outside the ambit of the judiciary system. Some elders disregard this, but let's face it, their work is cut out for them spying on current members of the congregation, and gathering evidence and conducting hearings on those that choose to remain accountable to Jehovah's Witnesses.
Keep on loving your family.
And then one day, I hope and pray, one day you'll realise that you're free. No elder will care about calling you in. Hell, no congregation will consider you theirs to worry about!
All the best in your journey, and in discovering who you really are.
