Hmm - I think I would tell her that you are interested in learning about horses. She will probably be thrilled. Many horse people don't go out of their way to push their hobby on friends/SO as most people will ask if they are interested.

If you want to learn about horses, I would check out your girl's horse library and magazines. Something like this book might be useful - https://www.amazon.com/Horses-Dummies-Audrey-Pavia/dp/0764597973/ref=sr_1_38?keywords=horse+books&qid=1566351268&rnid=2941120011&s=books&sr=1-38. Or you could check out the public library or a tack store so you can see what appeals in terms of horse books.

Practical Horseman has a jumping clinic column that analyzes people's form over fences that might be useful in terms of showing. https://practicalhorsemanmag.com/training/jumping-clinic-beezie-madden

Good Luck!

Horses for Dummies might be a good place to start. I’ve heard good things about it.
