i don't see how poly and sharing is healthy for her, i would think she would prefer stable relationship,
I'm staying out of this thread and these topics until I have a more complete experience of the game itself and can talk with less ignorance, but I did want to just wave a small representative hand here to say that these things are not, at all, mutually exclusive.
Intimate relationships involving more than two people are just that, and they can cover the spectrum of good to bad, healthy to unhealthy, the same as any other relationship can; most unhealthy ones fall apart quickly, because the need for good communication and consideration for and with your partners is multiplied. That larian chooses (or seems to be choosing, judging from other people's descriptions - as I mention, I've little first hand experience with the game yet) some of the most unhealthy, predatory and toxic stereotypes for polyamorous relationships turns what might have been welcome representation in media into another instance of destructive stereotyping that does more harm than good.
