Alison - I'm sure you are wishing he had made these changes a long time ago. But he didn't, and you had to start with your own healing process. Think about the lighthouse story - we start moving on, walking our own path, but shine the light back from time to time for our partner. It is really hard to do this -- to start healing emotionally, but also leave open the possibility of change. I think it is completely understandable when we see signs of change in our partner to have a whole range of complex emotions.
I think it's good to sit with your sadness. I am guessing with some time and space you will sort out your feelings.
If you were ecstatic, I would be more worried and would advise you proceed cautiously.
