Like many others, my wife couldn't care less about the trains, and only tolerates me dragging her on excursion runs.
However, She has bought me trains for Christmas several times, so I know our love over rides the dislike of spending the money on trains.
I've gotten her interested in a couple hobbies over time but it fades after a few years.
She seems most content to just watch TV and do family oriented things.
But after 26 years we are pretty stable in our ways and we still enjoy taking time out to just be together.
Take Care and God Bless one and all.
