All of us feels jealous to everyone we envy so much and I guess mostly girls or woman got that kind of attitude. I admit that I feel jealous also to someone who is successful than me or have a good relationship to someone but it doesn't mean that I am gonna ruin their life. In my own behavior if I feel like I am jealous to someone I will just said it to my self that maybe it's not yet my time and I will just wait for the right time that I will be happy also like the person I get jealous off. Jealousy is part of humanity and that is the real fact so whenever someone get jealous to us let's just talk to them in a good way and give them an inspiring advice even if they talk bad behind us and trying to take us down. No cure if jealousy I think.
