After reading your posts and the responses from everyone else, I'm struck by the fact that you or anyone else have not addressed the illness that your wife is suffering. My most vivid recollections of your wife's posts include that she's been diagnosed with PTSD, and she has a problem with believing that everyone except jws will be destroyed at Armageddon. Though I would like to encourage you to investigate the history of the WTB&TS, as many others have, I would also encourage you to look into why Cognac was diagnosed with PTSD in the first place. This condition usually attacks people who have been to war or endured periods of unalleviated mental and/or physical suffering. Has the belief system of the WTB&TS caused such a condition in your wife? Please, for both of your sakes and the sake of your marriage, get joint counseling to better understand the current condition of your wife's health and mental well being. In so doing, the counselor will probably be able to explain to you why Cognac finds this board so desirable. It is a place for her to vent and question in a safe environment.
Please also understand many others use this board for the same purposes Cognac does. It is very painful to be shunned by your friends and family for any reason. Many people have been disfellowshipped for "sins" that have no realistic atonement. For instance, if a WTB&TS teaching doesn't make sense to you, how can you ever convince yourself that it does? When I was a jw, my jw husband was extremely mentally and physically abusive. Doctors and judges deemed him so dangerously homicidal and suicidal that he was committed to mental insitutions on two different occasions. When I filed for divorce, the elders gave their standard advice; be a better wife and wait on Jehovah. When I told them that I was going to follow through with the divorce, they advised me that I wouldn't be able to remarry until I could prove adultery on his part. By then, I'd been through almost seven years of torment and was by no means interested in remarrying. But, for me, it was the principle of the thing. I was literally running for my life and did not have the time or inclination to wait around to see what he would do, adultery or otherwise. When I explained my situation to them, the answer was the same; obey the WTB&TS or else. I offered to disassociate myself, but the elders chose to disfellowship me instead.
But I digress...Follow through with a thorough investigation of the reasons behind your wife's illness. Allow both of you the freedom to seek answers from others besides the WTB&TS. Understand that many people have been hurt by the society. Only then will you have a reasonable chance of keeping your marriage together.
