My husband didn't want an excess of details, either, but I anticipate a lot. My method of coping was to be as prepared as possible by reading journal articles and following the posts on this site. I also assembled a list of volunteers for help with various aspects of daily life, and sent out an update e-mail to friends and family (I always had him proof this first). As it turned out, we needed less help than we thought, but everything was in place if it was needed.
So, to answer your initial question ... I probably thought about things too much, and he too little - but as a team we have managed fairly well!
