I've really been thinking about this thread - for a number of reasons. I have had clients for years, and with some of them it can blur into friendship and occasional lunches but this relationship seems a bit too close for comfort.
With most advisory relationships, one would try and improve them if it seemed to be faltering but ultimately one would just shrug and move on.
Forgive me for this, but I am going to ask two things:
(i) were your feelings for him entirely appropriate? I ask because you seem to mind the cooling of the personal relationship as much as the professional relationship.
(ii) is the excess of anxiety being produced by fee pressure at work. Do you feel secure in your new job?
