I responded to that earlier. SHE IS NOT SAYING SHE"S MONO. She's saying "not with X, not as a secondary"
You do realize that the you are the one arguing against the dialogue in the game, right? You are reading monogamy into a person who clearly expresses an interest in having others in the relationship. Halsin doesn't threaten her, Wyll does. Wyll would demand monogamy.
You never, ever, explained why Wyll, Karlach, Lae'zel, Astarion or Gale would threaten her, but Halsin not. Except that supposedly, this somehow happened off screen.
Well, I think it didn't happen off screen. I guess we are at an impasse. Do you have proof it happened off screen?
Also I'm not sure in what world the line "In truth, I don't think I'd want to be your spare lover. I'd always want more of you than you'd have to spare. Better perhaps to bow out with dignity." implies "clear interest in having others in the relationship." Except if you read the line in the completely other direction, somehow.
