1.      Put your energy in developing self-confidence. Jealousy is often a sign you are uncertain about yourself. You cannot believe your lover prefers you above all the nice and attractive girls and guys around. You’ll only accept this simple truth once you become convinced yourself you are attractive and lovable. One exercise is writing down all your qualities. Read this list through regularly and add one item every day.
2.      If you have no good reason to be jealous, don’t take it out on your lover. Don’t try to alter his or her behaviour, but realise it’s you who has to change. Talk about your insecurity. This gives your lover the opportunity to let you know you’re special.
3.      If you cannot get rid of your jealousy seek help from a professional.
