I have been trying a strategy of when I have questions or concerns I write them down (so I won't ruminate over them -- but by documenting it I know I will address it at *some* point) and then periodically try to weave into the convo with H when he seems receptive.
Just a thought- I read an article recently in which the H who had an A started a private blog for his W only. He used it to answer all the questions she had, but answered as he was ready. It seemed to work for both of them as the H didn't feel attacked and the W slowly received her answers.
