We need advice!!!

So my fiance gets pretty dang jealous. We're long distance for a few months and whenever he even hears about me talking to another guy he gets kinda ticked. He said he just doesn't want to share me with anyone and his confidence just isn't up to par. Don't worry he's not controlling at all! He's just doesn't want to feel like that all the time and we're afraid it's going to last even after we're married (July 22nd! <3). Do you ladies have any advice for getting jealousy under control??
