Not really though, she did have feelings for him when they were friends in the village. She was going to confess when Alistar exclaimed that he wanted to marry someone rich, breaking Magary. It was in chapter 22, also when Magary experienced amnesia, she was affectionate with Alistar and had no malice. It's why I want homegirl too to win in the end, she changed because of Alistar, they followed each other until now and is the only one who knows Alistar's true personality.
While it would be cool seeing Alistar with someone more attractive and richer. Having Magary be the end goal is more genuine than to follow Marla for fetish.
EDIT: I just reread this chapter. Yea she was disgusted and did it out of spite, but doesn't she like him? Yo im confused
