People who are jealous are insecure in the love they receive. They are worried that you will run off given half a chance, and they must therefore watch over you and be concerned when you are not within sight.
Be sure to show your love, and reinforce the constancy and commitment you feel. If your partner is being reminded constantly that you are there for the long haul, they are less likely to doubt every moment.
