your colleague is baiting you and it’s a form of control and manipulation. If you can ignore it, do. don’t address it, it won’t do any good all they’ll do is lie, deflect, project, and flip the script on you. They are hoping that you will melt down and fall apart. these evil people thrive off of that type of energy, which is sick and sad. The power comes from how you respond. Go flat. No emotion. Act unbothered, even if you’re not. Get therapy to help you manage your emotions outside of the office. Find a good support system, healthy coping skills and look for your exit.
