I mean I can understand we all feel that way at some points in our lives, but at the end of the day it seems like all it does is hurt that envious person cause it doesn’t solve any problems.
Not at all. Its a wasted emotion and only ever causes grief.
Jealousy is a misplaced sense of ownership, and we don't own anybody else. Not to say that I've never been jealous. And you're right. It doesn't solve anything.
I don't identify as poly, but have never been jealous. It always seemed to be such a negative emotion to me and counter productive.
Accept someone for who they are and what they do, not who you would like them to be.
Simples!
