First, congratulations on your chrismation and many years!
Second, welcome to the board!
Third, (and finally answering your question) your ROCOR friend is wrong and your priest is correct, insofar as chrismation alone being sufficient (although I think his reasoning is off). You'll find a number of threads around here on this debate, but the long and short of it is that historically, the Church has not had a universal practice for receiving converts from other Christian groups. Some are received by baptism while others are received by chrismation alone. I would argue that we do not accept other baptisms as valid; we do, however, believe that the grace imparted at chrismation retroactively completes the baptism, so long as it was done in a proper manner. In other words, the prior baptism might have been an empty shell, but it was filled with grace by your Orthodox chrismation (giving you an Orthodox baptism!). As a practical matter, though, I would suggest that it is your bishop's and synod's place to determine the proper means of receiving you. So long as it was done in accordance with their pastoral guidance, I think you'll find that nearly Orthodox Christians accept it as being valid.
