At the beginning of a relationship, an abuser may say that their jealousy is a sign of love.
Jealousy has nothing to do with love.
It is a sign of insecurity and possessiveness. The abuser may question their partner about who they talk to, accuse of flirting, or be jealous of time spent with family, friends, or children. As the jealously progresses, the abuser may call frequently during the day or drop by unexpectedly. The abuser may refuse to let the partner work for fear they will meet someone else. In the beginning the abuser may say that this behavior is because they are concerned for the partner's safety, need to use time well, or need to make good decisions.
