PHTHONUS or PHTHONOS
The Greek word "phthonos" is derived from phtheirô: the feeling of displeasure or jealousy produced by hearing of the prosperity of others or a state of ill will toward someone because of some advantage they have experienced.
The verb form phthoneô means "to be jealous of" and from phthiô: to pine or waste to shrivel or wither or to ruin.
According to some traditions Phthonus was said to have had many wives and killed most of them because of his suspicions about them being unfaithful to him.
His female equivalent was Nemesis
the goddess of jealous retribution.
