OKAY so this is an easy question on the surface but there's actually a lot going on. Let's dissect: so you can totally opt out of Valentines Day. Ignore it's happening, roll your eyes at people being gross in public, buy candy when it goes on sale. It's cool. HOWEVER before you start shitting on it or pretend it's not happening, check in with your boo, see how they feel about it. Things aren't always about you and if your SO wants to celebrate, try to meet in the middle, otherwise, resentment can grow if there are unmet expectations and/or hopes. You don't have to go big to acknowledge it. Just spend quality time with each other and make it a fun day.
