Autonomy Flirting/Mischief

I have been playing the sims 4 for about 2 years and ive never had this problem. But recently all my sims are flirting or doind mischeavous things. Even if theyre in a relationshp, have the loyal  trait or if they dislike mischef . Ive tried mods to prevent sims from cheating such as "Always be loyal" settings. Its really annoying because i cant have my sims to interact with literally any non household sims without them cheating. Its really ruining the gameplay because i hate cheating so much because it gives them tense or sad moodlet for like 2 days for both of them, adds a guilty about cheating sentiment which makes being around that sims give them another negative moodlet so i just create a new household. Please fix this because i am actually losing my mind with this.
