Sparks
I agree that no further contact is necessary. My anniversary was a little more than a month ago. I had a multi tiered approach where things would get more elaborate depending on how she took things. I started with some small gifts based on things she mentioned she liked before.

She was very grateful that I remembered, but at the same time said: I thought our anniversary was 5 days ago and you forgot. Which I know it's not true seeing how much she is a stickler for remembering dates.

Either way I think WAW don't want to be reminded of all the pain they have caused, and would rather the day go unmarked. At the same time I think most of them would get offended if you didnt remember either. What is it with women and damned if you don't damned if you do.

Either way the minimalist approach is the way to go. You have done enough for today.
