How to Deal With Jealous People?

Basically when dealing with a person who has a tendency to be jealous you can do one of two things. You can either walk away because most people will always be jealous due to insecurities or past experiences. Another thing you can try is building their trust in you and always be totally honest with them in hopes one day they will just be able to fully trust you and that will bring them comfort. In all honesty I believe a serious conversation and the ultimatum that the relationship will end might just do the trick but you have to mean it.
