Never said you wanted both? Sounded like you wanted to try to salvage a relationship with her after starting the harem and breaking her trust, no?
Did you actually read any of the dialog between Yrsa and MC in their interactions? Because it seemed obvious to me anyways exactly where Yrsa felt the relationship was going, and MC encourages that concept implicitly throughout their contacts. He initiates pretty much every level of intimacy (up until she jumps him in the haunted ruins) and she's made it quite clear exactly what she's looking for. Why would she ever believe he doesn't feel the same as her and/or accepts her conditions when she spells out what she's looking for and he responds by advancing the relationship?
No, that's just you assuming. What I want is to be able to let yrsa down gently. Obviously I don't know what the devs have planned for this, but I don't want to have to choose between apologising and trying to repair the relationship or just cutting her off completely. Ideally, I want the MC to explain that they never talked about being in an exclusive relationship and if she isn't interested in the harem plan that he'd like to remain friends. Becouse I like yrsa and I'd like for the MC to keep helping her, even if a relationship is of the table.
You ask me if I've read the dialogue, but I'd like to ask you the same thing. Let's go over the events, we'll ignore the first meetings and the ritual becouse they're not very significant.
So the first event is the stone thing, which starts of with being able to compliment her, but she actually prefers if you don't and ends with a friendly conversation and a classic hand on boob accident, nothing that directly points to either of them being interested in a relationship with the other.
The second event is meeting her daughter, obviously you're growing closer, but nothing happens here that wouldn't happen the same with a normal friend. Then you meet nox with her, you get some options to compliment her or peek at her in the bath, let's say you didn't compliment her, but you did peek at her, like any young man would. Then the MC did the only thing so far that might indicate a desire for a relationship, which is kiss her cheek. Certainly proof that he's interested, but not a declaration of undying love either.
Then they go hunting for that cave, nothing interesting happens here.
Then the ruins, the MC compliments her once and you can ask about the poem for various reasons, let's say we choose viking cultural interest. Draugr happens, leading into, as mentioned before, a steamy, adrenaline induced kiss, initiated by yrsa, not the MC.
Next thing comes after being captured, yrsa visits the MC, tells him she's falling in love with him and the MC doesn't answer.
Then he leaves for the raid, meets yrsa, she tells him she's starting to like him (which seems weird considering she said earlier she's falling in love, but that's neither here not there) and then she catches him in the act and runs away.
Now, what I see in all this is two people slowly growing closer, doing some light flirting, sharing an yrsa initiated kiss after almost dying and yrsa having clear feelings for the MC that he
never confirmed to share. In all this, the MC has never been more than a good friend who has an appreciation and some interest for a beautifull woman. Nothing here, indicates to me an exclusive relationship, if that's what yrsa wants, then she should have locked the MC down instead of just assuming he wouldn't want anyone else but her, which is just stupid. She's obviously free to not want the MC anymore after realising that he isn't pursuing her exclusively, but crying, running away and discarding any and all affinity between them is a gross over reaction, becouse he's been nothing but a good friend to her and hasn't been leading her on by pretending she's the only one for him.
