Does divorce take effect with the statement, "You are here, I will call your family to end the matter," intended as a threat? And is the wife considered returned with the statement, "If what happened was a divorce, then I have taken her back," or "I consider that a divorce"?

The phrases mentioned are not explicit pronouncements of divorce, so no divorce occurs without intention. Your statements, "If what happened was a divorce, then I have taken her back," and "I consider that a single divorce," do not constitute a divorce and do not affect the marital bond. If a man believes a divorce has occurred based on a condition, but that condition was not met, then no divorce has taken place.
