Although I am not a JW, never have been, I can speak from some experience. I saw my wife of 20 years totally morf from a loving woman and mate into a JW robot. Base on your story I think you should strongly consider bailing out now and live a normal a life as you can. I certainly don't know you or your wife, but I think your wife will be "on your case" for the rest of your life if you don't.
I've told my story several times on different active topics on the forum. I am ex-Navy and while at sea (in Japan. My ex-wife was a Japanese National), and the kids in school, they came knocking. The rest is history. She kept her involvement (free bible Study, going to meetings, etc.) a secret from me until I found out by accident (found a watchtower magazine) 9 months after she started. Although she tried (more like play-acted) to be the loving wife, it was quite obvious that her purposes in life now were focused around what the WTBS/JWs wanted her to do, not what she previously did as a loving mother and wife (and she was a very good wife. We had a good life/marriage/family). She started dressing and acting different. Letters to me while at sea were just a listing of bible quotes. After I discovered her involvement she tried her best to get me to sign up, and our children (thank God I did not, nor did I allow the kids to). Several times, on meeting nights, I tried to get her to go out for a nice dinner, or just a night out to a movie or something. Each time she called an elder (I suspect) to get permission, and each time she was told to attend the meeting rather than go out with me, and she did. One night I got angry with her and demanded her and I go out. She said yes, but again called someone (an elder I guess), and no sooner had she hung up the phone she was out the door (literally running) saying something out "dieing spiritually." During these times when I tried to just be a loving husband I felt like I had to get permission from my father first just to go on a date with my wife. Of course all of the holidays we celebrated together as a family were not as they had been in the past, and her participation was totally out of the question. On Saturdays, really my only free day of the week, I would try to set up a picnic, or just a day at the beach. It seemed she always had to clean her KH and be gone the entire day. It's amazing, and still bothers me to no end, that the elders had, and still have I suspect (we were divorced in 2003), total control over her.
Sorry to ramble, but based on what I went through, and you probably know this already, you essentially have two choices; have a normal life as you see fit, or have a life as your wife and the elders see fit. I wish you all the best. Whatever you decide, stay in touch with the good folks on this forum.
