Your wife had character for having answered the question to the best of her ability. The trooper followed-up and interviewed her in an appropriate manner. Your wife can go about with a clean conscience and not have to worry about something coming back to bite her later, like her ex finding out about her permit and reporting her psychiatric appointment. It's good to know that the ISP are scrutinizing the application process. What I worry about are the questions that some applicants might not answer truthfully and ISP not finding out about.
