> I disagree with that completely, like honestly people that prefer monogamy generally do so because they are either afraid to be alone, because it was what they were brought up on, just don't want to deal with being rejected a bunch before hooking up that night, or they are romantics.

That's a bitter remark. I think there's a lot to be said for having a life partner by the age of 30 (there are movie tropes about this), generally from a psychological and sociological point of view. If you don't look early, you decrease your chances of having it by the time it gets really hard to find mates at 35+ Pursuing a monogamous relationship necessarily requires you to be a functioning adult, capable of engaging in a negotiated relationship. How well you tolerate and negotiate, is the primary method by which both members determine the value of the relationship. This is unappealing to people who are psychologically undeveloped, damaged (insert millennial infantilism joke here) or simply have a personality that is incompatible with such a relationship...which can often be traced to a problematic upbringing. I'm just repeating part of what you've said with a different interpretation, but the general statement was just grating.

How functional can somebody be if they think nothing of slandering their only-ever girlfriend a “slut”? I just hope he’s not in the mature-adult age-bracket yet.

I feel so sorry for you. Not because we have different opinions, but because you’re somebody that thinks nothing of calling your only girlfriend a “slut”.

Protip: if you want to argue that non-monogamous sex is cooler and better, your argument will be stronger if you don't call your girl slut. I mean, she is doing what you argue is good, so shaming her weakens that.

Well she was really promiscuous, I'm not shaming her but I get it certain words offend certain people so I should filter what I write.

I’m really confused now... you’re advocating for promiscuity, but also calling somebody out (with unfathomably crude language, but you’ve tried to explain that) for doing what you’re advocating? Is it because she’s female and you’re not that you feel entitled to contrast your behaviours? Did you not know she was promiscuous before getting with her? Did you not care? Did you feel ’unspecial’ when she went her separate way or indulged her alternative passions whilst with you?

Don’t use the word “like” so frequently.
