I recommend you take some time with this. If you are anything like me, the duplicity you will be forced into for a while will be smothering and seem unbearable at times, but the end result will have a potentially better outcome than I have had.
One thing to remember is, first and foremost, if you choose to leave the religion the choices other people make are not your fault. You are not leaving them if they cut you off. At first post, you strike me as the sort of person who won't abandon friends just because of a religion. That is great. Some of your friends may not abandon you, but you can comfort yourself with the fact that any who do cut YOU off, you have those who don't cut you off as proof that you didn't cut anybody off from you.
The religion separates and divides. It sees everything as black-and-white, us-and-them, friend-or-foe. You seem already to have come to terms with the fallacy of that viewpoint. That is good. It is a very healthy realization.
I'm 33, married, and 4th gen (on both sides). I DA'd in December of 2005, and while I miss my family terribly (everyone but my wife and a few ACTUAL friends chopped me off cold-turkey) I can honestly say I haven't once wondered whether I should go back. I will never be one of JWs again.
It is tough to be in a family full of people who believe in Shangri La, just over that next ridge in history, come to kill everyone that isn't like them. It is doubly tough to admit that you don't believe in Shangri La anymore.
Welcome. Feel free to vent by PM if you need to. Or vent here. One of the best ways to hang on a little longer is to find another outlet before you blow up at them.
