My wife and I have a similar situation. I can't really sit and watch tv, and she loves to watch crime shows, and stuff like that. I typically sit with her during dinner, for about an hour at least, sometimes 2. Then I go to the computer and play a game or two till it is time to crash, which is about another hour or hour and a half. During this time, she does her evening routine, shower/bath, lay out her clothes, and fix her lunch for the next day. I have asked her if it bothers her if I am in the other room, and she says no. I would hope that she is being honest with me. I don't want her to feel alone, or neglected, but I am just not that into watching tv.
