Just wanted to make one little point of clarification. If you look up the words disfellowshipped and disassociated, they are synonyms and mean exactly the same thing. As usual, this is just more JW word play. It's a distinction without a difference. So, whether you were disfellowshipped or disassociated probably doesn't have any legal relevance either.
We all know JW's are famous for their silly word games. Another example: I was always taught to say I was "fortunate" as opposed to "lucky" as the latter term was a superstitious one. Again, if you look up in the dictionary, both words mean the exact same thing.
Another example: the obvious (nonexistent) biblical denunciation of major blood fractions as opposed to minor blood fractions which are not even mentioned in the bible.
You might tell her you weren't disfellowshiped for fornication, you were disassociated for shagging! If she can't see the obvious difference, well, there's just no reasoning with JW's.
