So, you are still waiting for his response to your letter, right? And now he is sending emails saying "let's talk", but not saying when, and limiting what you can talk about?
If you were playing tennis then you would be on one side of the net, and he would be on the other, with all the balls on the ground around him. It's his turn to hit the ball over the net. It seems to me it doesn't matter if you send emails or don't send emails, there is no reciprocation. You can't get a volley going. My prediction is that this will go on until you reach your time limit. So either you tell him there is a time limit, or you wait it out. What's the difference?
