If you have been married for 45 years petallus why had this cropped up now?
I think the answer maybe headphones for you both so that you can share the room and one watch TV while the other uses the laptop but it should be equal. Can't you encourage him to go to some of the games instead?
We have been married for 44 years so are just behind you and we met in 1966 so I should have known what I was getting into! When we retired we moved to Malvern so he was within a sensible distance of Aston Villa and he has a senior's season ticket. Today he has gone to watch a match in London on an AV bus so he left home before I woke and will get back around bedtime. Important matches he watches in the sitting room and less important ones in his study on a smaller TV. Sometimes we disagree about this but not often. I am quite happy for him to record and watch after I have gone to bed. That allows me to read in bed, which he doesn't like, and then he can come up and put my book away and switch off the light. It wors for us. We are lucky that we can be together - or not.
I do hope your compromise works, you must have made many over 45 years.
