It's not impossible to overcome a jealous nature if you're willing to put forth a bit of hard work for the good of your relationship. The first step is admitting that you have a problem and discovering the root of the problem. Jealousy stems from a wide array of reasons: abandonment issues, fear of being shamed, fear of being wronged, fear of loss of love, and so much more. Tell yourself that your concern is simply not true and that you will be greater than your fear.
