Yep, "conditional" vs. unconditional friendships is yet another one of those "let's put things into neat little boxes" oversimplifications.
Here is what I state regarding JW friends:
I had many associates, some were OK, most I could live without. It would not matter if any of these folks learned the TTATT. They would not necessarily be a better "friend" because of it.
I had 4 true JW friends. I do not consider any of these "unconditional" or "conditional". The degree of conditional response is the degree to which they are "mind controlled", which really translates into the level of cognitive dissonance they experience ultimately. The greater the CD at a given moment, the more likely they are to respond with a controlled response, since doing anything else would betray their belief system. They cannot help it. If/when they learn TTATT, and are ready to accept it, our relationship will pick up where it left off.
And of course, there is a threshold for what will be tolerated in any relationship. A friend doing your wife obviously crosses that line for both relationships. That is not the same thing as being shunned by JW friends, (although I am not excusing that behavior at all).
