I like this topic, Nancy. I am tempted to move it into our new "Caregivers" section, because your husband, and other spouses, are in a sort of "pre-caregiver" stage, where they don't really know what is happening or what to expect, or what to do.
It is ironic that you are busy on this forum posting about the problem of spending too much time on the forum. You are obviously sensitive to his feelings, so it is not like you are neglecting him. One idea is to let him know that among other things, this very topic is one of the things you are discussing on the forum. Another would be to invite him to have a look at the forum with you, and to share the experience with him.
Though like David I can't speak from personal experience about a spouse, I did notice similar effects on friends, co-workers and family members. Once they figured out that I wasn't going to die, and would be back at work and still functional, they stopped wanting to know anymore. The difference for me is that I can spend hours on the forum, without bugging anyone around me.
You are caught up it now, in fact at about the peak of intensity, and it really will die down after a while. Many find that just making a treatment decision is a huge relief, and certainly, if you are doing treatment, that becoming a postie is one as well. Tell him to hang on, you'll be home for Christmas.
