Hi Leander,
You have received some excellent advice. I am in the same boat as you, except I've got about 3 years head start. It has been a very difficult journey. I've heard it likened to finding out that your spouse, whom you believed with all your heart would stay true, has cheated on you. From that point on, you don't know what to believe.
After all, if they (the WTS) misled you about one thing, all of a sudden you doubt everything that was taught to you. But, not everything that was taught to you was wrong. Learn to hang onto the good and let go of the bad. It takes time.
Someone earlier mentioned to read Crisis of Conscience if you haven't. I also highly recommend his second book, In Search of Christian Freedom. You will have to keep these hidden from your wife, but they will help you tremendously.
For me, I am to the point where I still attend the Sunday meeting, and nod my head when I am in a group of JW's. I cannot afford to let my true feelings be made known at this point, but I am coping. I am finally starting to come to grips with my own spirituality. This board is my outlet.
Many on this board are now athiests. That is understandable. Some have found churches that they attend. Others, like me, feel that no organized religion is the answer, but I do feel that I have a close, personal relationship with my Creator. My feelings may change in time, but for right now, I am content with where I am at.
I wish you the best. Please keep us posted.
