Sorry to hear about your plight indi’, it’s real, and it’s frightening.
From my experience you might try looking at your wife’s situation from a slightly different perspective, although the view is not pretty and it can be discouraging.
There’s a good chance that your wife is looking at associating with Jehovah’s Witness for social reasons rather than doctrinal ones. Any amount of trying to explain doctrinal goof-ups by the WTB&TS as a way of persuading her intellect will fall on deaf ears.
More importantly she may have seen or found something in the communal ‘spirit’ within the congregational group that she has met which lights her fire, something she’s missing in her own life, including something you can’t offer socially.
Unfortunately this is a sign of ‘cult’ influence, which may be a difficult psychological problem for your wife to visualize let alone over come.
I just wanted to stress, you could be wasting your time trying to influence her decision with doctrinal issues. It’s the social magnetism, which is the most difficult to overcome because its influence transcends logic.
Check out some of the recognized books on cults, their recruiting techniques and what to expect, if not for your wife because it may be too late, for yourself as a source of preparation and confidence for the steps you may have to take one day on your own.
