Romances have become one of the number 1 cringe "features" in RPGs anyways (imagine if a party member betraying you rather than luvin' you had become a "feature" requested and you get an idea why it's become so shallow -- it's nothing surprising anymore, plus it's something to be ticked off a list, which both is the polar opposite of character depth).
There's a lot to say about how romances play out in RPGs too. The formula of gradually leveling up companions, unlocking ever more dialogue and eventually, as the "big price", pardon me, banging them, has always been juvenile to the max. But then that's probably the gaming industry for you, which is comparably still in its infancy.
I'm not holding my breath that BG3 is going to stop that trend in the slightest. (Which is is fine, I'm then just going to ignore all that stuff.)
I actually played a game a long time back with no romance, but instead centered on your party members reactions to your choices and the reaction of your soldiers and people to your actions. For example very early on if you make to many morally gray or down right evil choices one of your heavily good aligned allies sets up a trap for you as he thinks you will become a tyrant if you are allowed to become any stronger, but if you end up taking more good actions along the way and change your path before the betrayal event comes up. He will change his mind and warn you about it, help you defeat the attackers, then willingly subjugate himself to your decision as to his punishment. Knowing that what he did is treason and by law he should die for his betrayal. You can execute him which makes your soldiers respect you more for remaining true to the law, but your people will dislike this because he was beloved by the people for being an honorable man. You can also show him mercy and let him live, but your soldiers will lose some faith in your conviction to hold true to the laws and some may leave because of this. The people on the other hand will love you and your kingdom will grow larger. You can also banish him which makes both sides happy, but only partly and you lose that companion.
