Having this would allow a sim that a player has created to keep their couples faithful even when not active or when they are in full auto mode. If a sim has this they spur any advances and cannot be split up unless that sim is under the players control. I think it would be nice to see a faithful trait added that you could buy with lifetime rewards. Fine, but there should be better ways to counter the constant 'flirting' around that sims do! I bet Sims 4 is just as bad. I get why, it's so players can get the most out of who they want their sim to be with. It is so easy to bed and date any sim around and splitting up couples is so easy it's pathetic. The Sims really do need a faithful trait.
