I wish I was completely secure and devoid of jealousy. But no, I'm not that lucky. I have, from time to time, felt it and struggled with it but I think I'm dealing with it well. I try to get at the source of why I feel it and work on myself to effect the changes required to become free of it. And I don't lash out at others for making me jealous...it's entirely MY issue to deal with.
And the same with envy, sometimes I do resent others for having when I have not. I get over it. I consider it part of being human and flawed. Maybe someday I'll be more...enlightened, but I'm not quite there yet
