I started out exactly where you are 3 years ago. You are not Morbid.
My husband does not understand this at all, would never spend any time with the subject, and early on just sort of passed off the discussion as one of my tidbits of the day. He had no interest whatsoever, and really ignored mine.
However, during the past 3 years, when some news tidbit would show up and I was able to thoroughly discuss it (pro and con) or if someone in passing mentioned the case and I was able to discuss it (pro and con) he began to sit up and take notice of the deets I could discuss.
Now, each day he sends me a text message in support of my investing the time watching the trial. Each lunchtime he calls to see how it's going. Each evening he sits beside me as I read the posts in the other threads, catch up with the polls, read through evidence again to refresh my memory, and asks questions along the way.
While I will most likely never follow a case this closely again, this is an experience that I am glad he has seen as valuable for me, and has made the choice to support it.
