If he has expressed he doesnt want to talk to you, then I would say you should respect that. I wouldnt advise calling him either. Even after all teh contact me and my ex have enjoyed, I ONLY started phoning him last May, after he had GIVEN me his number and asked me to call him sometime. Again after all our recent contact, I still havent phoned him, I let him call me. Alot of communication has been by email whilst he was with ow.
I agree with Jack and Snodderly.. leave him be and dont contact him unless its urgent. Let him feel the full weight of his decision (I did the same, only contacted him in REPLY if he contacted me). What I meant above about htem having to see you is if they WANT to see you.. the same for Silver... I have been suggesting to her that she accepts contact and olive branches from her H, NOT make calls to him herself or initiate contact.
