Here's how we use Jealousy / Envy
Envy - wanting what someone else has AND being very happy for them that they have it.
Jealousy - wanting what someone else has AND being angry/frustrated that they have it and I don't.
When I move from envious to jealous I have to be cautious because the next thing that seems to come up for me is feeling resentful.
My jealousy is more from a fear based location not that I want to own someone but that I'm afraid (thinking of relationships) that what he has is either better or will "water down" what we have together.
I believe that you don't feel jealousy and I'm envious of you for it
