Usually when I experience jealousy I see it as more of a collection of emotions than as a single one. Sometimes my partner will be talking on a subject with somone that I cant contribute and I feel the dim one in the room. Or simply if Im at a loose end when my partner is spending her time elswhere.
I suppose if you know theres a specific reason for why youre feeling something it seems less of a deal.
