I suggest gifting your girlfriend a subscription to a cultural exchange program that lasts a few months or more. It could be a language exchange program or even a virtual cultural exchange program where she can connect with people from different cultures and learn about their customs and traditions, all while gaining language skills. Alternatively, you could create a cultural exchange experience for her at home by cooking a meal or hosting an event that features the culture she is interested in. You could also consider gifting her a book about cultural exchange or a scrapbook to document any future exchange experiences.
Or you can get her a star map with the date of your first kiss.
