The e-mail interaction sounds good. Way to go. I'd like to weigh in on the anniversary issue. What I did was send an e-mail saying "Happy anniversary. I know it is odd, but I do appreciate the years we shared." In your situation I'm not sure how much reminiscing I'd do. I think that for us post-D people that this is primarily about making a new R and forgetting the old one. Essentially starting over from scratch.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
