Are there other places you can take your S for vacation? Are there new traditions you start? And it's ok to feel different things at different times, heck, I go through the full range of emotions daily. One of the most basic (but hardest) principles of DBing is forgiveness of self. If you stumble or begin to spin then just let the stuff wash over you and continue to go through the motions.
As far as being mysterious goes, just don't offer up info. If the spouse digs for it then give pieces instead of the whole story.
