Jealousy

Jealousy is when we fear losing a relationship
or a valued part of a relationship
that we already have.
-Brene Brown

Jealousy is the fear of comparison.
-Max Frisch

Jealousy is a terrible thing.
It resembles love, only it is precisely love's contrary.
Instead of wishing for the welfare of the object loved,
it desires the dependence of that object upon itself,
and its own triumph.
-Henri Frederic Amiel
 
The knives of jealousy are honed on details.
-Ruth Rendell
