First of all, welcome aboard!
Isn't it sad that because you have changed your belief, people will disown you for it? Unfortunately, the people in the congregation will base their friendship on your status in some building rather than basing it on what kind of a person you are.
What you've done is built your life upon a foundation of the JW religion. That is what you've based all your actions, decisions, and achievements on. Now, the foundation is cracking and is going to crumble. Everything that is built on that foundation such as your wife, family, friends and lifestyle will come crashing down once that foundation crumbles. It's going to be a mess, but you may be able to salvage a few bricks here and there, and use them when you build your new life. Let's hope your wife is one of those bricks.
As for a new foundation for your life, may I suggest yourself? You can't go wrong there. I wish you the best of luck in your situation.
