TW: Death, and suicide.
My boss is super nice, and is usually very caring, but I always felt like she was weirdly attached to me. Her daughter died a few years ago, and she's told me she thinks of me as a daughter. I do lean on her for support often, but that's not the kind of work relationship I want.
Last month due to work, and other stressors I had a bit of a mental breakdown, stayed in the hospital, and was out for 3 weeks. In that time I decided that if this job was making me miserable to the point of wanting to die then it was time to leave.
I told my boss I was applying, and interviewing at places. I like to keep open, and transparent communication always. She took it well. She said they would miss me, but she understood.
But as I've continued looking she became a bit…snarky? For instance I mentioned that I don't know what I'll do if a place says they needed me right away, and couldn't wait till my 2 week notice ended. She replied “well I'd hope you would finish out the 2 weeks, and wouldn't screw over the people who have helped you.” These comments are really out of the ordinary for her.
I think maybe she feels some betrayal, and resentment. It seems like she felt this parasocial relationship went both ways.
UPDATE: I forgot to mention she got mad at me for telling a coworker I was leaving because the job stresses me out because “it's bad for morale.”
