Well, you’d think, but I ended up using MCCC to disable random flirting because people kept flirting with my Sim’s spouse while they were on dates, leading to “FURIOUS ABOUT CHEATING!!!!!!” sentiments that led me to rage-quit.
I also had an issue with a father-in-law autonomously flirting with his daughter’s wife. The father-in-law and the wife were good friends. (The randos who flirted with the spouse were strangers.)
I also rotated in to a romance bar between the same father-in-law and his son’s wife, which led to things like her getting an “embarrassed, caught cheating” moodlet whenever she kissed her husband. That was the first time I used a mod: MCCC to delete their relationship completely and reintroduce them.
