in my opinion, it measures how much you care for that person .. although it clouds your intellect and can often lead to misconceptions ..
you can trust someone you love, but you should love the person you trust ..
I am not sure jealousy is something you think about..I think it is a trait that you have or you don't have..I am not sure you can control it. And If it strikes, me if I am envious of something, I talk to myself and reassure myself, by reminding me of ways that I have been blessed. He or she may have that, but I have this.
exactly, your aware it is there, and so you react and control it. what I am saying..we can control it once it happens, but we can't really stop it from enetring our head. it is just there.
The difference is we control the emotion, others don't , the jealousy just takes over.
One possible explanation of the origin of jealousy in evolutionary psychology is that the emotion evolved in order to maximize the success of our genes. e.g. A jealous behavior, in men, is directed into avoiding sexual betrayal and a consequent waste of resources and effort in taking care of someone else’s offspring.
You could go along a similar sexual route that she wishes for her mate to provide and protect HER and not another woman?
Precisely. Though it may be of some use as a negative incentive to be loyal, achieve success etc.
It's just a pain. Has also to do with your self esteem. Some people just can't help it.
Possibly it wasn't something you cared enough about. Or not an issues with all cases
None, it serves no purpose
