Forgive me if you've heard this before, but like
I kinda love the Durge Gale romance, not just because Gale is very much my type and his romance is lovely, but because of the whole god parallel thing
Ok I've always been kinda bad at explaining this, but let me try my best.
Gods, at least in BG3, are embodiments of concepts, right? Bhaal is murder, Mystra is the Weave, Shar is darkness/loss, etc, etc. They don't have interest in things not related to their domain and they don't really have much personality beyond their job. That's what makes them so different from mortals. Mortals are complex and multifaceted, and while a god's domain can be complicated as well, they aren't anything more than what they represent. Bhaal doesn't like to cook and make homemade recipes, Shar doesn't give a shit about reading tomes by the fire, and Mystra isn't terrible and yet amazing at flirting. By all accounts, Withers is the funniest of all the gods, and that's because he's so serious and mysterious that he's funny. Besides the Withers thing, these are all traits that Gale displays just by being himself.
So, when Gale becomes a god, all those small things about him either get wiped or heightened based on how they relate to Ambition. All the enchanting things about him get erased and the things in the world he found enchanting become boring to him. His literal first words at the reunion party when he becomes a god is remarking on how boring he finds Faerun now.
Of course, Gale doesn't know this will happen, but that's kinda why I'm so fascinated with him and Durge as a couple
Cause Durge was created by a god. They were created by a concept and they were made to be a concept, meant to live a god's life when they've always been a person
If Durge wants to be anything more than murder or try to resist their urges, they get punished for it, with the two main examples being Durge accidentally murdering their adopted family and feeling so ashamed of their admiration of Gortash (platonic or romantic, your pick) that they write a whole prayer about it, begging their father for forgiveness. The only intimacy they're allowed is with their corpses for gods' sake.
So basically as Gale is trying to escape the Netherse orb and find a way to extend his possibly rapidly ending life by reaching for godhood instead, Durge (a reformed one) is actively trying to escape their old life by becoming more than a god in the most mortal way possible. By making friends, finding new interests unrelated to their domain, and just living through the human experience (maybe not human, but you know what I mean). It makes for a really intriguing dynamic even if they aren't dating, but I love it a bit more when they are. Makes their arguments about the Crown of Karsus a lot more interesting when you frame it as Durge trying to save Gale from living the life they once had
