Freeme, I am in a similar situation except a little more progressed in my fade. I've been inactive for a while, and my talks with my wife are progressing to the point where she doesn't get mad so much when I bring up things that I learn here. It's taken a while of gently introducing these things, making some progress, and also making her mad at times.
The last conversation we had, she surprised me by agreeing that meeting attendance wasn't so big a deal after all...especially with the congregation we are in. She mainly goes to the book study meeting because her group seems to consist of mostly balanced individuals who don't get all pharisaic on everyone. She regularly skips the school and service meetings and most Sundays. Also, I got her to agree that the WT society is a modern-day bunch of pharisees. I plan to show her this article soon and tie it in somehow with this pharisee idea and the Bereans and whatever else I can think of. I'll let you know how that goes.
You might find that over time, your wife will mellow out whenever you present new information to her about the cult she is still in...as long as you do so a little at a time and gently. The keys are being patient and presenting things little by little. Remember what the WT says about the "Adam to Armageddon" speech and how that turns off most householders? Too much information in too little time.
The same concept applies here, only we're trying to get our loved ones to see something much more beneficial.
Good luck!
