jealousy

Jealousy typically refers to the thoughts, feelings, and behaviors that occur when a person believes a valued relationship is being threatened by a rival. The word jealousy stems from the French jalousie, formed from jaloux (jealous), and further from Low Latin zelosus (full of zeal), and from the Greek word for "ardour, zeal" (with a root connoting "to boil, ferment"; or "yeast"). Jealousy is a familiar experience in human relationships. It has been reported in every culture and in many forms where researchers have looked. [1] [2] [3] It has been observed in infants as young as 5-6 months old and in adults over 65 years old. [4] [5] [6] [7] It has been an enduring topic of interest for scientists, artists, and theologians. Psychologists have proposed several models of the processes underlying jealousy and have identified individual differences that influence the expression of jealousy. Sociologists have demonstrated that cultural beliefs and values play an important role in determining what triggers jealousy and what constitutes socially acceptable expressions of jealousy. Biologists have identified factors that may unconsciously influence the expression of jealousy. Artists have explored the theme of jealousy in photographs, paintings, movies, songs, plays, poems, and books. Theologians have offered religious views of jealousy based on the scriptures of their respective faiths. Despite its familiarity, however, people define jealousy in different ways. Some even mislabel it as being protective of something or someone, when the fact is, it's really simply possessive jealousy itself; and many feel they don't possess effective strategies for coping with this form of jealousy.

that's a tough question to answer lol much as i would like to say that i'm not, but the truth is, i can get jealous very easily. i wouldnt say that i lack confidence or that i dont trust my bf, but if i see him talking very close (never happen before though) to another woman, i might feel a little bit jealous, i guess....or if he's extra nice to another woman, i will be jealous....

i think its the lack of self conidence

jealousy is a form of stupidity!

i think it has a lot to do with self confidence and our experiences but then often if we have had a bad experience it kinda niggles at our self confidence anyway im a jealous person and as much as ive tried not to be (gave it a huge effort to consciously think about it and trying to ignore it) it is just me and i know some people think its stupid or childish or whatever but they obviously havent experienced jealousy themselves...its not something one can control usually and i for one hate it...

lack of self conidence, lack of trust in the person... im not too jealous but i do get that way sometimes

It's a combination of all of what you've mentioned!
