More effects for a sim when he/she or them gets betrayed

I was thinking, for example when a sim catches his/her/their partner cheating on him/her/them they a sim gets only angry at the cheating partner but what about the person the cheater cheats with? A sim should also get upset at the other person, it would be realistic to add more effect for this if the the other person could be a friend, good friend, best friend or even a family member then it would hit even harder for the sim who has been cheated on.

Another example, if a close friend, romantic partner or a family member spread false rumors about a sim and that sim hears about it and sees it then the sim feels betrayed.

Plus it's weird that in the Sims 4 a can't accuse their partner of cheating on him/her/them meanwhile in the Sims 3 they can.
