I’ve seen a few similar posts but am hoping someone might have specific advice regarding cutting ties with an abusive ex-supervisor. For context:
I started working in this supervisor’s lab as an undergrad, and was hoping to go to another university for an MSc. My supervisor recommended I apply for a research fellowship in case I changed my mind (which I naïvely did), and then lashed out when I asked for references to other programs and refused to give them to me as he wanted me to stay in the lab. This was during covid so I felt pretty trapped + coerced into staying, but thought i’d graduate quickly and make the most of it. The next 2 years of my life were literal hell, as I tried to graduate and the scope of the project crept to an unmanageably large level. During this time, 2 other Msc students either left the lab or the program completely, a postdoc quit and everyone was miserable because of how abusive he is. When I finally graduated, he expected me to continue working for him despite me clearly stating my intention to leave, and was shocked/berated me when I handed in my official notice.
All this to say that, since I graduated last year, I’ve been doing some (unpaid) work for him from time to time as a courtesy and to wrap up some analyses from the project. However, the scope also keeps creeping, and now I feel trapped all over again. If I stop, he will sabotage my academic career, and likely take it out on all of my old lab mates who have become good friends (trauma bonded lol). How can I stop doing work for him as I genuinely don’t care about the publications anymore and would prefer to have zero contact with him?
