The worst part for me is not even a creepy advances, it's the fact that Shadowheart is more than willing to accept them. There could be some tweaks in the dialogues that could send the players different message from "I always thought and dreamed about this" to "It feels like a dream". Somehow let the players know, that she is enjoying it only because you chose it, not because she craved it all along, just didn't tell you about it. But the way as it is now, it's just awful.
I would personally find it a lot more disturbing and off-putting if the scenario was set up that Shadowheart is just some doll without agency that simply does what you demand of her on your request. This is too much submissive tradwife for me.
Feeling adverse towards Halsin as a character and his involvement I can understand, because that's just a personal opinion. We like and dislike different characters for a variety of reasons and they don't have to be fair or justified. But some people like their dynamic and that's a fair opinion as well.
A different question: Is it horrible if the romance is not perfectly spotless? I feel there is a certain bittersweetness to all the endings, some more, some less, and it of course always depends if you enjoy or can accept a specific brand of wermut in your romance, but does it really spoil your character's whole romance with Shadowheart? I mean, they are happy with each other in the end, no matter what thoughts Shadow had, in what must have been a very stressful time for her. Aren't they? Honest question, as I know there are several other absolute dealbreakers for people in the other romances too.
And I don't think it's ridiculous either. It just means that the character and her romance resonated with you really well, and you were deeply immersed in the game.
I am more in agreement with this approach. That Shadowheart has agency, preferences and interests of her own, but chooses to put those aside if they don't align with Tav's expectations of a relationship is to me a more honest and adult romance development that appeals much more to me.
