I too was madly in love with a Jehovahs witness... then I married her. Cured me of that.
But to your point.... What exactly is the rush? Not to be overly pointed but it seems that in a fairly short period of time all your questions will be answered. Her meetings with the ministers (called elders in witness parlance) won't last more than a week at most. Your 52 years old. at that age you know full well a little patience goes a long way. Relax. Let it play out. You will know soon enough just where you stand with her. Read up on this site and see exactly what the real life experiences of witnesses are understand that neither you nor her are different. Neither of you are special little snow flakes. The problems that the religion creates for them it will create for the two of you. Its a time bomb waiting to explode if your not fully ready and aware.
Relax and read up :)
