Here are three ways to reduce feelings of jealousy (adapt the steps if your partner is the one suffering):
1. You can only be jealous if you believe somebody has something that you do not have. Therefore work to appreciate what you do have. Above all, value your relationships as these are much more important than material belongings.
2. At the core of jealousy and envy will be a feeling that you lack love - particularly self-love. Try to understand why you might have lost sight of this gift and heal any insecurities and negative self-beliefs that you find.
3. Notice that the people you are jealous of, also have their own problems and issues. They are probably envious of you! You are complete when it comes to love and your natural/spiritual connections. Accept this and embrace the warmth and comfort that these things bring.
