Jealousy is not the same thing as love. Sometimes, people think that by feeling jealous about someone, they are loving him or her by being possessive or wanting ownership over the person. Jealousy is not love; it’s the fear and anger of losing out or being abandoned.
- Fake it. Portray a non-jealous facade while you work on overcoming jealousy. Eventually, working your way through your feelings, the facade will become real, but in the meantime you will protect yourself from appearing jealous to others.
