Is jealousy really such a bad thing? Or is it only bad when it doesn't motivate one to do better? I ask because as I've gotten older I've noticed that jealousy tends to play out in two ways: it either becomes the motivation by which one betters themselves, or it becomes the scapegoat, justifying one's insecurities. I've noticed in sexual relationships that generally when men are jealous(and not abusive), they tend to try harder to prove their worth, yet women tend to shut down. So which is it? Should we have total faith in one another, opening up the possibility of being taken for granted, or should we view outside competition as an impetus to better ourselves constantly?
