Jealousy is justified when you know you deserve much more than what you have ..
Jealousy is justified when you repent making all the wrong decisions confidently in past...
Jealousy is justified when you also KNOW that the situation will never change to better...you are dumped and screwed ...accept it for this life time and believe in theories of REBIRTH ...

Jealousy - always not a negative virtue
always does not sigh at others!

.............sometimes its SIGH on your presence and what you did to yourself!
