LOL, LMAO even. I'm going to be a bit of an asshole now but I'll do try to keep it playful.
That's a lot of words just to say you are into cucking. I bet it felt rather good writing all of that, especially that last line. But the gaslighting doesn't really work. You might have your preferences and views when it comes to relationships but you will find them amongst the minority if you only decide to look outside your bubble.
Now let me say this, I really don't care what kinks or interest you or anyone else has. (OneManArmy comes to mind) I really don't and never did, what makes you aroused and how you conduct yourself during your relationships is entirely up to you and I will not think less of you just because I don't share your enthusiasm for it. I just ask that you or others don't shove it in my face or try to trick me into it, especially when it comes to the enjoyment of my games, books, movies etc.
You go on about how flirty she is and aware of her position/attractiveness and yet she is rather dismissive of anyone that isn't the player character throughout the game, she is even so interested and invested in the main character from the start that if you decided not to kiss her during the Tiefling party she voices her disappointment. Which leads us into the rest of her romance/story. You said she changes how she interacts with the MC as soon as the stakes are raised and feelings are involved and that is true, true to the point that her investment in the MC leads her to reject any other advances from others or ideas of sharing.
But a person experiencing her story should not voices their concerns if a character starts exhibiting contradictory behavior and statements because a writer decided to spice it up out of nowhere with Mizora or Halsin? (Both scenes felt like they were tacked on after everything was already established)
As for your 'mature' outlook, believe it or not but the majority of people regardless of their sexual orientation don't consider it a healthy relationship for their partner to flirt with others or constantly fantasize and or pine for others. You might even say its a deal breaker.
And seeing how Shadowheart despite her claims of commitment goes 180 AFTER her story is finished and flirts and thirsts for Halsin no matter what, it is understandable as to why a lot of people are not pleased. People don't like being led on, in real life or fiction. So when a writer surprises you with a sneaky little cuck fetish you get reactions like these.
Now lets me be a bit sassy and do some relationship counselling of my own. No its not controlling to expect commitment in a mono relationship, no its not making a partner submit by asking them not to flirt with others and cheat on you. It's okay to have self respect, It's okay to voice your concerns and set down your deal breakers. There, I wont even charge your that
Aside from the very premature conclusions about my sexual desires, the rest of your reply was well worded.
I have a social circle where sexual references and jokes that are very on the nose is perfectly accepted and enjoyed, without any of us ever having taken those words into actual action or practice. So I don't read much into how the characters in BG3 interact in that regard, it seems that is how they have been written. Maybe the writers have spent a lot of time watching Critical Role and assumed that is how everyone enjoys their DnD banter.
