Welcome to the board. I'm a non-Witness married to a JW by the way. One argument I have regularly with my husband is how it is possible for a single organization to "own" the truth. Doesn't truth stand on it's own merit? That is, nobody can own it, and nobody can claim to have it all. Truth stands on it's own. Every action that you take is down the road of truth or it is not.
I won't even go in to the highly insulting comments he makes about my church and my beliefs. Even though I show greater mercy and kindness to my fellowman every single day than what spews out of the study materials.
So, no. The society is not the sole owner of the truth; it's not even the closest organization in our day to the "truth". The eternal truths about love, kindness, mercy is out there every day when you walk along the beach or through a park.

Now, what in the heck do you do if your entire life is invested in this organization, that is not what it claims to be? You have to start over. I find that exiting Witnesses have a much easier time of it if they start building a network of friends and associates BEFORE they make the big break.
This will also give you time to process all this new information, and figure out what it is that you really believe in.
This will help you in the storms to come.
