I've said not sure. I did threaten one T with a complaint though I had no intention of actually doing it. I wanted her reflections. She did damage me considerably and her conduct could have caused a less insightful person to go over the edge , which was my main motive that she should get how potentially tragic her conduct could become. Her supervisor was very concerned and much more clued in than she was. Her response when it came was less than ideal but I thought it would just have to do - you could go on forever trying to get someone to see something. It's understanding futility. I will add when I was discussing this with people they said her response may make you feel better or may make you feel worse. All situations are unique of course so I wish you well with whatever you decide ATAT - it's very painful when this happens.
