The Sims 4 romantic boundaries settings: What they mean and how to change them

Since the beginning of the series, Sims have never had a nuanced understanding of romantic boundaries, which can lead to lots of household drama. I'm talking about everything from accidentally flirting with your Sim's neighbor to intentionally getting caught cheating by your many spouses in the Black Widow Challenge.
