Again, none of us knows what happened here. Please encourage her to be frank about what she perceived. It is entirely possible that either a) you will actually agree with her and think that perhaps you need to look for another Rov, b) you will be able to help her see that she might have misunderstood or overreacted (after first validating her discomfort to her, i.e. “I can see you are very upset by this situation…”), or c)you will speak to the Rov and explain that whatever he said to her made her uncomfortable and you would like to understand what really happened, what his intentions were, and clear up any misunderstanding, if that is still possible.
Of course, there is one more possibility – she is a really hyper-sensitive person and the Rov did and said nothing objectively offensive, but he caught her at a bad moment. If that is the case, she still needs to understand that, and you have some thinking to do about your relationship. Hatzlacha rabbah.
