I’m a librarian and read an enormous number of books each year. I avoid new, popular fiction like the plague - probably 70% of what I read is nonfiction. I don’t think your husband is weird or has some sort of issue for preferring nonfiction. Just let him read what he wants while you join a book club.
I might read one fiction a year. Currently reading about the fault zones around Seattle. I like science and history. My reading allows me to take a break from people. I spend all day navigating people, it can be exhausting.
