AITA for having small talk at work?

A little background, I (23f) have been with my fiancé (40m) for about 2.5 years now. We have both been cheated on in previous relationships, but have never cheated on anyone or each other. This is important for later. We work together in a factory type job and see each other quite often. Some weeks more than others. He is quite the introvert while the older I get, I’ve become decently extroverted. I enjoy having small talk conversations with colleagues as it makes our 12 hour days go by faster. I personally hate the “work wife/husband” idea and think it’s very disrespectful. All conversations are completely work appropriate. The few occasions someone has flirted with me I immediately told my fiance of the situation and cut that person out of my life. The issue comes in, almost anytime he sees me talking to someone at work, whether male or female, he almost makes rude remarks about how he’s “too busy working to talk to 500 guys” or the occasional text along the lines of “who did you just say hi to” if I sees me talking to someone he doesn’t know. Many of the people, we talk to together but it only becomes an issue when I do it by myself. I’m really torn between seeing his point of view, but also just feeling like he’s trying to control me when I’ve proven time and time again I never had an inappropriate work relationship. So, aita for thinking he’s trying to control me rather than setting healthy boundaries?
