I think your W's reaction was very positive. It really sounds like she appreciates your thoughtfulness. So often these are seen as pursuing by the LBS.
By contrast, when I gave my W some roses a week before our wedding anniversary (we were going to be out of town on the actual date) she said nothing, got very quiet and did not really acknowledge my gesture at all -- in fact, you would have thought I had brought in a live rattlesnake and set in the middle of our living room. She was both alarmed and and cold at the same time (if that makes any sense), indicating she was very suspicious of my intentions, and for no rational reason.
When I later asked her to dinner to celebrate, she got angry and said, "Why?! There's nothing to celebrate!"
I tried to reason with her, telling her that she might consider our M a loss, but the anniversary also marked the start of our family, and it resulted in our two children entering our lives. This was enough to convince her to go to dinner (that and the food), but our M was not something she wanted to recognize, let alone celebrate.
So I'd say you are in a much better position that I was.
