At least she is curious, that sounds like a positive. I agree that you don't have to tell her anymore than suits you. I'm not big on the whole "mystery" thing for me, but that's b/c I'm pretty much a cards on the table kind of woman. That being said, I don't offer too much info either. What you did sounded perfect.
I know this is life on the razor blade for you and I'm really sorry. Enjoy all that you can with davedick gone.
