Yes, while you're in limbo, don't plan a grand romantic evening (pressure, trying to buy her love, highlight what's missing). Anniversaries can feel like darned if you do / darned if you don't!

You probably know I'm a romantic! Early in the day, I'd probably give her a single truffle and a card with no mention of the day but a simple expression of gratitude for something done (where there's no future desire or expectations)--e.g. "I'm thankful you gave me two beautiful children." NOT "I'm thankful you raised our kids for 10yrs." Hopefully, you see the second statement reeks of expectations. As an LBS, it's hard to do a tiny thing, easier to do nothing or a grand romantic gesture. If that's you, do nothing, but a tiny thing would show you remembered and care. The truffle or other tiny (<$5) item (not reeking of romance) shows you know her tastes. Doing it early gives her the chance to guide you if she wants to try more.
