I am going to attend a conference as I have been selected to a voluntary position and it is mandatory to meet up with the organizers. At this conference, my abusive ex-supervisor is chairing sessions and probably he is going to attend, he does not know I will be there.
I hate him so much as I was forced to leave because he was racist and narcissistic, travelling to another country with harsh conditions, it is a long story. Now I am working on the same topic with another nice supervisor.
No one knows what happened, but I am afraid of this encounter, I am so emotional and I hate him although he apologized via email after I left couple months, but I still have a grudge since he delayed my academic progress and I cannot tolerate with that, how I should react, ignore him completely, he is very awful person.
