I dated a co worker (I know I know NEVER again, I learned my lesson) and he ended up being a piece of shit , a bald, ugly cheap scrote who pretended to be generous and nice until he gets in my pants and dumped me as if I was nothing).
Anyways. Unfortunately we work in the same room. I don't work with him directly but we are in the same room.
I would like to ask how you would react if you have to see your ex scrote, for example, you go to the same gym, or you live close by etc. how do you react?
For example, at work in theory no one knows about us but he wants to keep the image of the "good guy" and he greets me as if nothing happened but he knows I deeply hate him.
I am very outgoing so I talk to everyone and I hang out with many girls there. PS: he was quite impotent.
Today we bumped into each other in the bathroom and greeted me. I completely ignored and pretended he wasn't there. It was so good.
What a satisfaction. I avoid him at all costs and don't even look at his face.
there's no right answer to your question, you can do whatever you want. You can be nice/mean/awkward, the only thing that matters is your wellbeing.
