Her-Unremorseful, Wayward ex wife
With my current SO, we have found that writing things out helps. I tend to throw out too many questions and information at her at one time. She gets kinda overloaded and anxious. So, I have tried to write more things down in an email and then she can answer and address each topic more specifically and without the pressure of having to give an immediate response.
If your BSO asks you the same questions repeatedly, there is probably the fear that some day, your answer will suddenly change (trickle truth). Maybe just start writing out your answers in a proactive manner. Dear, BSO I know you frequently ask about... (insert your answer) Sometimes having something in writing can be helpful. Have your written out a timeline?
Based on your registration date, I would assume that dday was very recent. The repeated questions may continue for a while. Think of these times as opportunities to help reassure her. Maybe start telling her the answers in advance, before she asks them.
