the amends step says "Made direct amends to such people wherever possible, except when to do so would injure them or others."
emphasis is mine... the fact that you haven't responded to him is a response and he needs to let it go..... you have no responsibility in the matter, really. IMHO he is not approaching doing amends in a healthy way. you don't want to hear it. that's good enough and it isn't necessary that you tell him that - sounds like he is fishing for contact.
like i said - the fact that you aren't taking the bait is your answer. hang on to your peace and find your joy!
