Chris, the DR book addresses a lot of your questions. It's been a while since I read it, but I think MWD says all your questions are natural. These things will eat you up if you don't eventually address them. And your WW will need to understand that you'll have these questions, and she'll need to open up to you as part of the healing process. But I think it's too early in your sitch to start bringing these questions up.
