@mw1525 - The No Jealousy LTR, when it's working as intended, grants the sim who has it immunity from the repercussions of their actions that would otherwise lead to jealousy. Their Romantic Interests and partner, if they have one, won't be jealous of them. Reputation hits can still be a thing though, there is no control over what the nosy neighbors across the street or other busybodies in town might think whether there is any truth to their allegations or not.
Sorry if that still doesn't seem logical, but I didn't design this silly game. I'm just passing through here. :)
