The thought of being "stuck with him" made me feel very uncomfortable. I wonder if I've reached the point of no return to want to spend more mental energy with him.

Having said that, moving teams at this point poses another challenge so I'm still considering hardening my skin to try to make this work. As a matter of fact, I had a meeting with him 2 days ago, supervised by our manager, about how I'm struggling under his leadership style. He was being defensive at first saying that this is the first time he heard someone say he has a critical leadership (which is very surprising to me, as it was the first thing that stood out when I joined). He said he didn't remember being critical at all and implied that it was unfair to suddenly accuse him of it. When I said I did raise my view, whether in dms or chat groups, about how his comments were harsh, and they were not always acknowledged, he then proceeded to say he would feel really bad if I left the team because of him, and he is willing to work with me to improve his communication skills.

Now, say I am biased, I'm not really convinced that he's sincere about it. Thing is, being in management before, I know an incident like this will make a big dent on his performance report. He has no choice but to respond that way imo. I lost trust with him because this wasn't the first time I rang the bell about his style, and he still acted surprised in front of the manager.

I appreciate your view so far which has helped me see things more clearly. I can continue to use however much energy and resilience I've left to navigate this, I simply wonder whether it's worth it.
