Since there is only one short dialogue about the Halsin situation and no follow up, it's hard to say one way or another. Based on other Astarion lines about the importance of Tav/Durge and his insecurity about sex, it does give the impression he's not really okay with Halsin. And yes, I know that the writers want me to climb Mount Halsin, but it's not what people take away from the game.

There is also this little thing that it's only Tav/Durge, who gets two partners. There is no dialogue option to tell Astarion he is also free to search for new partners.
