Can jealousy be good for a relationship?

Quoted: Lauren Papp, Ph.D., a University of Wisconsin human development and family studies professor who has extensively researched intimate relationships, agrees. “[Chronic jealousy] is not a positive sign for the relationship. It might be tempting to think that someone is more interested in you, or cares for you more, because they express more jealousy or possessive behavior. But jealousy really is a negative sign of insecurity in the relationship.”
