Group dynamics are a very interesting and sometimes not a very pretty thing. A few months ago, I decided it was time for me to leave a group I had trained with for many years. Their was no animosity in this decision; I had some great times with them over the years and considered many of them good friends. Quite simply, my interests in what and how I wanted to train had diverged from what they were offering, and it felt like it was time to move on. Rather than saying "sorry to see you go, good luck with your future endeavors", my attempt to part on good terms and as a friend were met first with complete silence (no communication for nearly 2 months), followed by hostility and accusations of dishonorable deeds and conduct on my part, including some of my "friends" there indicating that they no longer want any kind of association with me until/unless I "fix" things with the dojo. This feels very much like the "othering" described in Rory Miller's Facing Violence; now that I've chosen to leave the group, they have to make me into the bad guy. Very sad and petty IMO, considering the years of service and teaching that I've contributed during my time there. Has anyone else run into similar behavior on leaving a dojo or training group?
