I don't know if it's just me being more sensitive to reactionary nonsense but I feel like in the past few years people have gotten really weird about infidelity and monogamy in general. Don't get me wrong infidelity is always shitty behavior but people tend to have really weird overexaggerated guttural reactions to it nowadays that I feel like just weren't there before like 2020.
More broadly people tend to have more unhealthy expectations from their monogamous partners, like tracking each others locations always, texting all day long, not letting people hang out with the opposite gender, expecting many hours of attention from them every single day etc.
