Tbh with valentines day, instead of thinking about how all the supermarkets are just capitalising off cringy couples, ignore all the must do date ideas for valentines, and instead just think of it as sort of like thanksgiving, but instead of thinking about what you're thankful for, think about the things and people you love, and give yourself a little bit of self love too. You don't have to celebrate it in any particular way, but if you are going to do anything then do something that you know your partner will enjoy rather than picking something off a list of valentines date ideas, you don't have to do something all cute and uwu with them, but just do something that you'll both have fun doing just to show your appreciation to your partner for being so great!
