Hi Marilyn,
Welcome to the forum!!
Your instincts are definitely serving you well on this topic. It's important that you enjoy undivided attention from each other each week in an interactive way in order to keep the "in love" vibes strong. TV per se is not the issue; it's that you're missing something when that is the default option for much of your time together.
It would be great to get out of the house during some of your undivided attention time, so you feel like you are doing something special together.
Here are some ideas for time, considering that fatigue is a factor:
--Sit on a park bench tossing bread to ducks while having a conversation exploring a topic of mutual interest.
--Pack up a picnic to enjoy together on a nice evening
--Take a drive to enjoy a scenic point, route or even the landscaping in the various homes you past
--Go to a place where there is dancing; order a glass of wine and enjoy the romantic, fun vibes. Perhaps get a few slow dances in for yourselves, too!!
--Sign up for a gentle yoga class together.
--If you can, go for a slow stroll on evenings when the weather is amenable - even if the stroll is short.
--Do an exercise DVD together, selecting an exertion level appropriate to your capabilities.
--Volunteer at a NICU unit together to hold babies, or at a nursing home to play cards with the residents.
--If you have a shared expertise, minister to others over the internet together. There are sections here on CF for almost anything. Are you a prepper? Got that here. A flat earther? Got that here. Can you share some of your life's wisdom with new Christians? There's a forum for that here, too. Want to fellowship with people your age bracket? Got that here too.
--Select a topic of mutual interest and purchase some books to study together and discuss.
--Find a Bible reading plan and read aloud to each other every day, discussing things that jump out at you in verses.
--Play some card games or board games together.
Hopefully this will help warm up your imagination for some types of things that might be mutually entertaining for you.
It's great to see you here, and I hope you enjoy your experience on this site.
Blessings,
E.
