Do you believe that your bestfriend can be your worst enemy ?

I have, my ex best friend wanted to be apart of this other crowd in high school that I didn't want any thing to do with also if she didn't have all of my attention she would get so upset. We talk every once in awhile but were not close at all.

Yes, I believe that can happen. I had a friend for 20 years and one day she just wouldn't speak to me anymore. I don't think it was envy of sorts but, just from things that happened from the past.

yeh i agree i havent faced any betrayal in lovefrom my best friend but turning into enemy due to jealousy. i cant understand why do people have to bring jealosuy amongst each other when they are good friends or when they share a good transparent relation. Due to jealousy i have lost many of good people around me, than i start thinking that theres some thing wrong in me.

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.

It can happen, it hasn't happened to me and I dont think it would happen to me because we're too alike but have different interests if that makes sense.
