My husband's emotional affair

[justpeachy]

He also told me last night that he deleted all of her contact information from the places he had allowed it to linger -- email addresses, chat room ID's, the gaming community he met her on. And he said that, where it was possible, he even blocked her from contacting him.

I don't know if he contacted her at all to tell her he was doing this, or to say "goodbye" or anything (didn't think to ask until this morning...). But, do you think he should do a "No Contact" letter to her just so it's clear? I worry that she'll reach out to him again while he's still withdrawing from the addiction, and he'll get sucked back in (since that already happened once). Or should we just let it be?
