Musings and a question

So, I have a question for all my blogger-ites out there...

Have any of you ever had someone very dear to you suddenly walk out of your life, with real no explanation, then show up again suddenly after a good deal of time? What do you do? This person was my dearest friend in the world, one of few I can remember past lives with and that I cared for like a sister. She was my priestess. Last November, she just up and left. When I asked why, the answer I received was vague and has, to this day, left a hole in me. Recently, she has reappeared in my life through mutual friends. And while I have been hesitant of direct contact, I finally decided that if I did not ask the one question that has threatened to eat me alive, I would never be able to lay her absence in my life to rest. Who ever said that two people needed to walk the same path in order to be friends? I have yet to receive a reply, but am sure I will over the next few days. Perhaps it is foolish of me, but I felt that I had to relieve the weight of this from my chest once and for all, regardless of the outcome. I would like to lay it to rest at Samhain, so that I can start the new year with a fresh outlook and a healed, though scared, wound from the loss of her in my life.

Have any of you ever experienced this? What did you do? As I recently explained, I don't have many close friends, which means that those I consider such are so special to me that I feel as though a part of me broke with her departure, especially at that point in my life. I'll just be glad to have closure.. even if we never speak again.
