Does saying "you are divorced" in the context of narrating a story, with the presence of satanic whisperings, constitute a divorce, and does it affect the current marriage?

Mere whisperings or doubt about uttering divorce do not entail anything, because the default is the continuity of the marital bond. Marriage is established with certainty, so it is not removed by doubt. Therefore, no divorce is incumbent upon you, and your wife remains under your marital bond. The most effective cure for whisperings is to disregard them.
