lightbrite – if you are talking about a Gadol Hador, I think you should listen 100%. Otherwise, it depends on a lot of factors.
In this case, my impression (although I might be wrong) was that it wasn’t a matter of following his Rav blindly, but rather that he had concerns and wanted to break up and his Rav encouraged him to do so. I could be wrong. I guess my assumption is based on the fact that in order for his Rav to have known enough about the situation to advise him, he must have asked his Rav for advice.
