But you can romance Karlach and Halsin at the same time and Astarion and Halsin at the same time too, so that means they are poly too. How come SH doesn't agree on poly with Astarion or Karlach? There is other explanation though - SH/Astarion/Karlach treat Halsin no more than a fling, casual sex source for Tav and they ok with open relationship if Tav is.
This other explanation falls flat because it's something the player has to assume. The second you have to assume that's just how it is, that's bad writing. Reality is that Halsin was added late as a romance option and they wanted him to be poly/open, thus they changed the other companions reactions to fit that. If they wanted us to think it was just a fling, they should have dialogue for that. They have not. And even then, them being okay with a fling is awkward, because then you should be able to ask for a fling with all companions, which leads to a can of worms they probably don't want opened.

The dialogue about casual sex being encouraged as Sharran is unfortunately a complete contradiction, and thus not canon, because it is otherwise mentioned that Shar looked down on sex without purpose (aka sex that helps with doing her bidding), which makes sense because she is or at least was the goddess of, amongst other things, seduction. They therefore had to actually do it in secret or come up with excuses to do so, which means she obviously had action, but not to that extent. Also explains why her relationship with Nocturne is implied to be platonic. This is established during her entire Sharran path in act 3 amongst a few other scenarios and implications, where she will eventually break up with you despite still loving you because she has no time for you.
And even if they were to make this canon, it would not explain why she would still be like that in act 3. After all, she went through 2 acts of character progression and as we already established, she has changed into a mono person who wants Tav alone.
