The first time you must have been a bag of hormones on legs, as well as all the other things that go with A's. I salute you.
O hope I never have to deal with a second time - even if it's easier.
It seems to me that if you want / need all the details you are going to have to create an atmosphere where he feels safe with telling you. He needs to know that altho' he will see you hurt, because I believe that undoubtedly it will hurt you, it is something that will ultimately let you heal and move on. Show him the books with the sections explaining it - you know which ones they are - you told me about them when I first came to these boards.
Good Luck and let us know how you got on.
