She isn't "opening up to him" because her intuition is telling her there IS something wrong with wanting to know every single detail. My husband and I have been married for 7 years; he figures what is past is past and it doesn't matter. I agree that you have to share important info about diseases, etc, and even some info on previous dating, but to be interrogated is a sure sign of controlling behavior that will only get worse with time, not better.
