It seems to me that maybe e-mail is the one form of communication where you have a chance to get through to him. Face-to-face and phone both seem to blow hot and cold.
So, on the one hand I'm not sure I would reply right away, certainly not to pursue him or to declare your undying love. But on the other hand you can keep the lines of communication open and have the advantage of being able to compose your thoughts and run them by your editor(s).
If you do decide to reply, don't tell him you're NOT done, or that you are waiting for him, or that you love him. Maybe just ask him questions like:
"When do you think you WILL know what you want?" or "How long do you think I should wait for you?" or "Maybe you don't know what you want, but wouldn't you agree that your actions suggest that you don't want to be with me?"
