Jealousy in romance is like salt in food. A little can enhance the savor, but too much can spoil the pleasure and, under certain circumstances, can be life-threatening.
This was the noblest Roman of them all. All the conspirators, save only he,Did that they did in envy of Caesar;He only, in a general honest thoughtAnd common good to all, made one of them. His life was gentle, and the elementsSo mixd in him that Nature might stand upAnd say to all the world, This was a man!
If poisonous minerals, and if that tree, Whose fruit threw death on else immortal us, If lecherous goats, if serpents envious Cannot be damned; alas; why should I be?
We envy only those whom we feel ourselves to be like; we envy only members of our reference group. There are few successes more unendurable than those of our close friends.
