Please tell me if you think I am wrong or if this is gaslighting like behavior.

I work at a place that has contracts with people and we will sometimes go to different countries for work. You can work with some people for up to 6 years. Or a few months. I completely understand that working alongside people for so many years that professionalism can go out the window on days of hard work etc. BUT. Some of my co workers are pretty passive aggressive. I understand that sometimes people are passive aggressive because they genuinely don’t like confrontation. I don’t believe this is the case with these individuals however. I personally believe that passive aggressive behavior can be very childish in a work place because as adults, things should be communicated. I am openly communicative. Would I be gaslighting someone in thinking that them being passive aggressive has everything to do with them and not with me? For example, you’re upset that I didn’t help you with something, so instead of telling me that you act irritated for a while and give me the cold shoulder. I ignore it because I assume it has nothing to do with me since you didn’t communicate that. You being irritated is not MY problem, it’s yours. Not in an insensitive way either. In a way that I’m not letting someone else’s mood affect mine. I only ask this because I don’t want to make people, in the future, feel invalidated if I’m in fact thinking in a toxic way.
