To am extent you're probably right, but she's also been objectively mean towards the MC and even if she's not the MC, it was still mean of her to make a comment about the MC looking shabby bc she only has 2 outfits to rotate. It's also none of her business.
Like another commenter said, if she was suspicious of cheating, then she should take it up with the person. Or gather evidence first before she tries to insert herself in the MC's conversation with ML.
Her actions were annoying (maybe even infuriating) because she was wrong on many levels, but her going against the FL was probably the cherry on top.

If she's suspicious of her cheating thats a different story imo. like you said it should be confronted bc cheating is a no no hands down. What irked me personally was her passive aggressive comments not the suspicions and i kinda feel like thats what really got ppl in the comments riled up. tbh she shouldnt be going towards the guy if shes suspicious of cheating either but to her directly. Maybe the FL would be nice enough to actually explain whats going on but I can't say the girl will be like "yeah okay that makes sense" and move on. She's already made that sort of comment to her without even thinking that maybe the FL has some sort of problems going on in her life so i wouldnt be surprised if she made more assumptions and jumped to conclusions on her own to the point of deluding herself into believing their true.
Is it just me, or are ppl hating a little too hard? Like, i was pissed off too, but seeing how mad ppl are just made my anger disappear
