Ex-T sounds unethical but he's not going to admit to anything, and as long as it's your word against his I'm not sure if reporting would have any results.

You make reference to your current T but I wonder what their take on all this is, especially the in-person meeting, which I'm not sure how it would be useful for you. Agreed with Out There that maybe it's not resolved because it relates to a lot of older stuff that needs to be dealt with. Maybe the best thing is to work with the new T and try to put this behind you.
