EDIT: Just had a prime example of this, my eternally faithful husband got falsely accused of cheating because a friend gave him some flowers, he's flirty so the flowers acted as impetuous for him to flirt back, I cancelled that so it never actually happened but even so his wife got upset, a minute later after apologizing to his wife it comes up he has been falsely accused and she feels betrayed, he now has a cheater rep and they are heading for a divorce as she wont be civil to him in the least, at least it's not a challenge game so I can reload my last save, I'll accept it if he had cheated but just accepting flowers isn't an affair.
I've had something similar happen and this was before the latest patch - Star was a teacher in Twinbrook and Alma Drill wanted to cuddle with her once Star finished reading her book for work. I caught the action in the queue before anything happened, had Star strike up a totally platonic and professional chat with Alma, and figured that'd be the end of it. Star goes to the library to meet up with her wife Space and get some work done from "home" - next thing I know, Space stops working and accuses poor Star of cheating!
I didn't have Star apologize because she didn't do anything wrong so that didn't help matters. It happened to be a tournament challenge file (New Job, New Digs or something like that) and it was annoying enough that by the time I realized I inadvertently failed it anyway, I figured it was the simiverse telling me that they weren't meant for the tournament, no matter how far I had gotten by that point. On a happier note I went back to a previous save before Alma cornered Star, got Space a Level 3 visa in China, got them both to drink the Young Again potions they created themselves and are now in happy stasis at the old Pidgin place.
Anyway, this attraction system isn't going to help at all.
At least I know that if I decide to make either one of them males using the CAS cheat and have natural children, there's the possibility I could end up with a pyromaniac who can apprehend burglars and sneak around in the process...provided I can keep them from talking to other people.
