Is AUTHOR wrong in the post ? POST : Basically, my boyfriend of 3 years just started his residency as a surgeon this past summer and works in a hospital in the next town over. I had an appointment in that town last month and got to visit him at work for the first time. While waiting for my bf to come meet me at reception, I happened to see my ex (from 5+ years ago), he greeted me nicely, we exchanged small talk, and he went on his way. I didn't think much of it and went on to have lunch with my bf. I did not bring it up, thinking it's a big hospital and the chances of them actually working together may not be that big. I was wrong. About a week later, my bf sends me a pic of his surgical team posing with a young patient and my bf and my exbf were standing right next to each other (surprise, ex is a surgical nurse. I had no idea). My initial reaction was haha that's funny... and then I remembered how jealous my boyfriend can get. It doesn't happen often, but on the rare occasion he becomes the green monster, he becomes an obsessed maniac who needs constant reassuring that I've only got eyes for him. We've had discussions for literal days about how I will never leave him outside of him messing up big time. It can get tiring, but I deal with it because I love him and I empathize with him and I understand we can all get insecure sometimes. However, it does concern me how he will spend days or weeks worrying about his perceived volatility of our relationship, which led me to my dilemma. I decided not to tell him that he works directly with my ex because I was worried it would affect his performance. He is new at the hospital and I don't want to throw a wrench in an otherwise successful residency by causing him anxiety or anger whenever he has to rub elbows with the ex. I know he is an adult and he should learn to handle his insecurities in a healthy way, or at least leave them out of the OR, but I can also see how it may be difficult for him and I want to be able to protect him if I'm able.

AITA for not telling him? I've considered what could happen if my ex tells him first, but my ex seems to be in a great long-term relationship (by checking on FB), so I see no reason he would bring it up to my boyfriend. They don't hang out outside of work and I can't picture a scenario where the conversation would come up while they're on the job, so I'm kinda banking on it staying a secret. IMO, not mentioning it and letting my boyfriend complete his residency without this issue distracting him is a better alternative to telling him and potentially creating a problem where there wasn't one. Am I completely off base?
