I mean I’m sure you could if you really want. Maybe try writing or some such. I would probably just read non fiction though. It’s an entirely field of interesting shit that you don’t need to have a creative bone to be fascinated by. Some people just can’t connect with a narrative story all that well but there is no any shame in that.
Not helpful just wanted to say Jane Austen is great and your girlfriend had good taste! Okay good luck:)
