While I totally get where you’re coming from, unfortunately, there is an actual logical answer to that question: Jealousy is one of those emotions that does not involve logic. Jealousy only involves “feels”. It’s purely based on emotion. It’s irrational. So when a man sees another man, who clearly has feelings for his wife, in spite of knowing logically (in his head) that that man will not act on those feelings, he feels jealous. That’s because his jealousy is in his heart, therefore it’s unable to share the wisdom his mind is privy to.
