Welcome aboard. When I was at the zone meeting, I was thinking to myself "we're going to see a lot of new members on JWN because of this" and sure enough there have been a few trickling in.
You'll find that there are a number of folks here in a situation similar to yours - dealing with a spouse that's in while you're waking up to TTATT. You're certainly not alone, and there's a lot of support here. You've definitely got a leg up on me, having never been baptized - I was born-in and almost made it, but at a weak, emotional point in my life my father pushed just the right button and I got dunked at 19. One more year and I would've been out of the house and could've had a normal life. Since you were never baptized, you may have better luck waking up your wife and keeping your kids out since she would've had to be a little lacking in faith to marry you in the first place.
Keep learning, and vent your frustration here so you don't blow up on your wife. Go slow in dealing with your wife, don't just dump all you learn on her in one big go. Best of luck to you in your journey!
