You can cease contact but you can't stop the conversation.
Like a mythical beast, one head appears after another, and endless conversations are had...in a vaccuum.
That is, I have found, one of the hardest things about silence. About endings without closure. About deaths and breakups and the missing of someone.
The conversation never ends, it just meanders and lingers and finds new parts of your brain to include. It is a nonstop rollplaying game with many characters, and only one player.
Sure, sooner or later the conversations become less frequent, less interesting, more predictable and circular. But they never are truly resolved. They are questions without answers. They are that jigsaw puzzle with a missing piece, right in the middle,and the mona lisa never gets her smile.
