Given that you have made this decision to tell him, I think it would be worthwhile to consider where you stand if he expresses that he feels the same way.
What I think is ultimately of no concern, but this whole situation has red flags popping up all over it. If he feels the same way would you be willing to wait two years for him? How would you feel if your confession was the catalyst for something occurring, he was reported, and lost his career?
If he does not return the feelings would you report him for inappropriate conduct? Because if he is not acting from some kind of attraction, I believe he has harassed you and abused his doctor/patient privilege.
