I don't think you did anything wrong by not texting her before. Now you know that's one of the things that makes her feel appreciated in a relationship, though. So it wouldn't be a bad idea to set aside some time for it in the future. Putting in the effort to do little things your partner likes such as that can help keep the spark alive in a relationship.
“This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.” ― Douglas Adams, The Hitchhiker's Guide to the Galaxy
