Welcome Dazed! And, yes, take it slow and easy on the wife. Face it, you've evidently been 2 years to get this far. Don't handle things in a way that will scare her "IN" even deeper. Help her to see that you are now a better person, better husband, better father even without the WTS.
Your situation is just another example of how the WTS handles members with problems. It gets rid of them. No, not the problem, it gets rid of the people. Boot them out! Can't waste any time (let alone any $$$) worrying about helping out a sinner.
Congrats! and hang in there!
