Break Up & Divorce

Struggling with my ex moving on 1.5 months after breakup with my friend. Now I have to work with both of them. How do I forget about them?

My ex and I broke up, shortly after my friend and her became really close and were hanging out all the time. I told him it hurt me to see them together but he was dismissive. I only had to be around them because we all work together. I find out through work friend that they are dating. I wanted him to at least give me a heads up, not ask for my permission. Now I have to see them together at work and it’s difficult. I also lost my mother last year and I’ve already been going through it before this. He had been avoiding me at work and it has created tension and affected the work environment. I called him to clear the air so we can all work together effectively and he admitted he handled this wrong from the beginning. I told him I’m not okay with it but I accept it and will not be in the middle of their new relationship. I feel hurt that my friend actively chose to pursue her knowing it would hurt me. I also feel bad that she moved so quickly with him right in front of my face. Do relationship like their last and am I wrong for feeling this way? What is the best way to move forward? I only have to see them at work so should I try to find a new job? I love my position and where I work but this seeing this situation unfold has really affected me negatively.
