Perhaps in one way it is sad, but in another it means that Father Confessors in the Greek tradition are selected according to their proven ability, experience and charism to guide souls.
My two cents: One's Spiritual Father ideally should also be your Confessor, and we should not change Confessors easily- too many cooks spoil the broth. The term "Spritual Father" does not necessarily apply to your Parish Priest. I suggest you ask your priest to suggest a a few Confessors for you and make an appointment to meet each one.
More to what ozgeorge says, you could go to the "Russian" (do you mean OCA? Or is it ROCOR, Carpatho-Russian Archdiocese or even Moscow Patriarchate?) priest for confession but attend the Greek church as your regular parish.
If it is an OCA parish, it is rather inaccurate (and many would term degrading as well) to refer to an OCA parish as "Russian" since the OCA does not identify themselves as Russian, they are American self-heading, are viewed as an American Orthodox Church and many of their parishes may only have a few Russians. As to the Antiochian Archdiocese, I don't call them "the Arabs" even though they are tied to Antioch since they have such a large population of American converts and other non-Arabs. As to other local Churches, although I do frequently refer to them as "the Greeks", "the Serbs", etc., I realize that I should probably stop, even though they seem to want to hang on to their ethnicity more. Maybe I should've started another thread on this.
