first and foremost, it sounds like you're interested in introducing more quality time. here are a few ideas that I have, most are things I saw my parents do:

• go for a walk, bike, hike, or something. but just walking around the block is straightforward.
• read a book or poem to her (if you want to keep it short and easy, to start, I recommend trying just one random page from the Tao te Ching) (I've linked the digital version, but get a paperback, they're tiny and you can carry them around easily)
• do a crossword together
• sit on the floor stretching & listen to an album from start to finish
• talk to each other, but not about politics if you can avoid it
• get some crayons and do some coloring books
• grow a chia pet (they're surprisingly complicated to get started)
• learn a card game, or dominoes, or backgammon

if all else fails, you could tell her about bitcoin ;)
