sigurd didnt really love marie. he loved nasha. but because nasha is taken, he aggreed to marie's feelings out of consolation. but now that he had learned the truth, his view and sentiment of his sister and father were more impactful to him due to regret and guilt of the past. so it was easy for him to neglect marie as he didnt have as deep of attachment. and his feelings for nasha has basically evaporated at this point. since he was already letting go of his feelings eversince he accepted marie. seeing nasha throwing tantrums and basically announced her plans to kill his sister removed any leftover feelings whatsoever.
Ahh I see thank you!! I still can't belive he could just leave her in pain at the church and never vist her once. And now she's going crazy from being addicted and letting herself get used like that, it's so sad.
Why did Sigurd leave Marie again? Like I don’t understand how could pretty much abandon her when she’s in so much distress for his sister. Like I get it his sister needs him but that’s your fiancé! Anyways, can someone please explain it to me, thank you.
