Jealousy comes from a feeling of inferiority and the tendency to compare yourself to others and not feeling good enough. It can come from a place of suspicion and insecurity – in truth it’s fear, fear of not being good enough.
Jealousy is not normal, nor is it a marker of how much you love someone or how much someone loves you. Observe how your body feels when someone is jealous of you and also when you are jealous. It doesn’t feel nice. Why should we accept that as normal?
