I feel like my boyfriend is far too friendly and nice to pretty women at work, how can I get him to see it this way?

Before he and I got together officially he talked to other women at work. He really just flirted a lot. He had a couple numbers but it never went outside of work with them. Only with me. We got close outside of work hours. We clicked. He asked me to be his girlfriend. He did a girlfriend proposal and everything. Though we ended up being together I find it that he’s still too nice to the pretty women he attempted to talk to before we became a couple. This one chick/co worker he’s always saying “Goodmorning” to and prolonging conversation with her. He and I work in separate departments but I pay attention a lot. I won’t be messy and say anything at work but it just seems odd to me.
