Re: How to get Sims to stop cheating/flirting with other Sims

@KhanistavvHonestly, the only way I know of to limit this behavior is with mods. This is something that has frustrated a lot of players for a long time (myself included), and it's definitely an aspect of the game that could benefit from some tuning, especially for console players unable to use mods.

Personally, I use the Wonderful Whims mod to adjust their relationship autonomy, so if you're a PC/Mac user and are willing to use mods, you can give that a try, or MC Command Center.
