My condolences to you, SJ- you're in a unique position now. She
  was your one and now she's not. Grief manifests itself in
  strange ways and even Spock was troubled in the relationship
  with his parents. It appears that 12 months is the appropriate
  amount of time to expect odd thoughts/feelings/actions from
  yourself, as, for some reason, we humans (and you are one of the
  same kind) seem to process large cognitive dissonance content
  over an entire four season segment. Just when you've taken a
  step forward, a seasonal reminder throws you into a strange
  place.

  You are unique and different, yes, but also human. I hope you
  allow yourself some leeway for at least a 365 day period from
  here. It is, all things considered, the most logical position to
  take at this time.

  Be well, my friend.
