Hello, well I am happy that you found something that is very interested b/c flowers on v-day aren't cheap at all. But a few ideas I can think of is to do something together that neither of yall have done before. For example, I love active activities such as rock climbing, biking, hiking, and such. So I would look at something both are interested in but havent done ever. It would help both of yall to get to know each other. Good luck with everything and hope this helps.
