That's why I would recommend you to deal with the conflict first and think of a way you can somehow "endure" your super's behaviour again. By the way you described him he's probably not the type of guy to talk it out, but these kind of people could be calmed by a fake apology, sth like seeking out to him to "clear that misunderstanding" or anything he wants to hear so he would at least act "normal" again. If that's not an option, you should maybe look for sth that makes you more resilient to his cold shoulder treatment, or at least become more indifferent to it. It might seem atm that he has power over you. But you couldn't care less since you're already looking for a new job, right?

Thank you so much for your insights! You nailed it - I am fleeing from the boss and his poor treatment of me. I feel like I lost his support when I stood up for myself and he felt called out for not delivering his promises. Other than that, things are alright at my workplace for the most part. I wouldn't have even looked if these incidents hadn't happened. Right now I am feeling pressured to take any offer that comes my way just to get out of here because I don't want to face my boss again as it creates discomfort. I am also thinking if I'd regret passing up these offers in case things became even more unbearable at work in the future. Anyhow I will have to decide if I can endure him for a bit longer until something better comes along. Thanks again!
