Even when I was in another relationship--this is the first time in over a decade that I am not--I always spent V-Day with my DH. Our wedding anniversary is the 15th, so the days leading up to and following those days were always spent with him. That has been our tradition since the getting to know each other stage.
I am happy that you enjoyed your V-Day. I treat it like a fun, lighthearted day. Complete with unique gift exchanges.
