W: "Yes. I know. I think he got the message this time that I don't want to talk to him anymore." ...
This statement makes me think that she believes this has concluded. I will wait and see how his next attempt of contact plays out.
That's the problem. Because it doesn't matter if SHE believes it, if it doesn't happen.
And predators rarely "get the message."
That's why transparency plans are needed. Whether you, strong-armed, set one up or whether you set it up as per above with a "you know what you need to do," the fact is that one WILL need to be put in place, because the pursue-ee can have the best intentions in the world, but if the pursue-ER ignores them, there's GOING to be contact, and that contact (even if it's negative) WILL set your wife back.
