I still think you should say something along the lines of "While I do not agree with your decision, I respect it. Please call me on X-day so that we can discuss the details of this furhter." And leave it at that. At this point, I don't consider this pursuing. I don't consider it pursuing because of the fact that he has told you over an email (sheesh) that he wants a D. You have a right to know more about paperwork, etc. Should he not bite and ignore you (which would be super immature), get your own L and prepare for this. Well, in the interim I believe you should talk to some Ls anyway (start calling around today).
I wouldn't sound overly excited when you talk to him. Just keep it clean and "professional"--like how you would talk to a boss. I am unsure of whether you should mention how you don't feel loved/wanted. Perhaps you could say something like, "I do not want to be M'ed to someone who does not want to be M'ed to me" should he bring something up...
I would like some more opinions on this. Not that I don't trust your advice soleil, but I just want to hear as much as possible of what people think of this because I'm really unsure of what to do. Thank you!
Accept that there is only one thing you can change in life and that is you
