ITIS,
well done old boy. it's amazing how much your story reminds me of mine, except that i made my break, and now months later my wife is finally coming to the point yours is already at. i have to say that the amount of responsible research you did into doctrine is AWESOME. you have really done a really good job with that.
i would say show her lots of love as per the advice already contained in the thread. show lots of love to your kids, although i'm sure you do. it's just that she sees that as an extention of love for her.
there will be hard times on the road ahead, but IMHO the hardest part is over. that intital conversation is SO hard. when my wife found out that i held to evolution over creation, she actually packed her bags and started off to the bus station.
but now more than ever, she needs to see that you are more or less happy because of your intellectual freedom, and that you are not some depraved looney because of this knowledge. she'll have a lot more questions in the coming months, but let her come to them on her own. and don't worry, they'll seem easy to answer now that you don't have to pretend anymore.
and along with nathan's comment to you, make sure that she knows that you have done all this because you do want to lead the family. that you want to lead the family down the intellectual (and spiritual) path that is most closely aligned with FACTS, not TRADITION.
two thumbs up man. PM me or email me any time you like.
