What inshockandhurt said could work!
Can you text or email her here and there, or is that out of the question?
Our experience:
We had two antiversaries really close together, the two days I slept with the OM and dday itself. For the first we went away. My BS thought it would be harder than dday so we went away to a convention of our 12 step fellowship....It turned out to be a FABULOUS weekend!
For the dday date (it was black friday) we were out of town with family, so we left the kidlets with them and went to a day long meeting of our 12 step fellowship.
Honestly we planned and planned for these. We made sure we had something totally different to do, that we would be in safe places if it was just too hard, and that there was someone to watch the kids...just in case it was tough.
What wound up happening is we created two really great memories.
And things that I think will turn into traditions!
What are her plans? Is she working?
Can you have stuff sent to her at work?
Could she plan a day out with a friend who knows whats going on?
If not I think the idea of planting notes in unexpected places could be cool.
Or having dinner delivered for her and the kids.
