I was in contact with my former T for about ten years. We had a really good, helpful therapeutic relationship and only ended therapy because I graduated and moved away. I usually sent periodic updates about my life and how I was doing. She would reply with encouraging things and sometimes little snippets from her own life (about pets and mundane mutual interests, mostly). I was grateful that goodbye didn't really have to be totally final, and I found that I had less of an urge to contact her as time went on. I would still be in occasional contact with her if she hadn't passed away. It always felt good to share important life milestones with her because she is the reason I'm still alive.
