Does conditional divorce before consummation take effect if it is contingent upon a speculative future event, and then this speculation proves to be incorrect?

So long as the questioner is truthful in his statement to his aunt that "you both did not intend to prevent her from attending the wedding for the reason mentioned," then no divorce has occurred for his wife due to that. He should not pay attention to the whispers of doubt that come to him concerning this matter, and he should completely and utterly disregard them because their consequences are dire.
