Obviously, your fiance is a charming guy who attracts women. That’s the good news! Who wants to be with a dud, after all? 😆 It doesn’t sound like he is cheating on you, from what you wrote, so I don’t think you have anything serious to worry about. However, if this flirting bothers you, you have to look at what in your own life, and more specifically in this relationship, is making you feel threatened. Your fears are not coming out of the blue. You must have some reason to believe that he will leave you for someone else and that this flirting is the “gateway” to abandonment.
My advice is to focus on your relationship and make it the best one possible. Flirting is a harmless way of complimenting someone — normally. Find a way to allow it to be part of your lives. 😀
