Valentine's Day

I don't like Valentine's Day because I thinks it kinda a stupid made up holiday meant to pressure guys into buying stuff for their girlfriends and I told my SO that I don't really like the "Holliday" and now he thinks that he needs to do something extra special because he thinks that I do like it but am using reverse psychology or something but I really don't like the holiday, however I did get him something incase he decides to try and do something, I bought a metal heart container and filled it with bullets and the card says "doses are red, Violets  are blue, here's some ammo let's go pew pew pew" but what can I say to keep him from spending a lot of money on stuff I don't want?
