First off if you have kids start allowing the friends outside of the congregation, and you and wife should start that too. When you leave you need a social network other than JW's. That's one way they keep people in. Obviously with kids you still want to make sure their friends are good influences. But start teaching them that they need to judge people on their character-not just their religious affiliation.
Probably your family is ready for a break from the busy life of being JW's, meetings twice a week, service on the weekends, family worship, etc, more if you're an elder/pioneer etc. So let them enjoy a weekend off, take a vacation and don't go to meetings, start missing stuff subtly more often. At first they'll just be relieved to sleep in on the weekend! Honestly, one of the biggest things I love about not being a JW is having my time to do with as I please. Not as I'm told to by the society.
SLOW, SLOW, SLOW. Like everyone else said. If you say too much your wife will jump and then she'll be on that righteous defense mode. "Get behind me Satan!" With everything you say.
Hang in there bud
