I feel bad for tohru, but I don't think it's the girl's fault either if she felt uncomfortable with it. She 100% could of worded it in a nicer way while still explaing the main issue, but she's a middle schooler so I'll let it slide. The parts we saw when they were a couple, she seemed like a decent girlfriend for the most part. Breaking up before even worse troubles & arguements is probably for the best of both, atleast
She knew to break it off rather than being controling and forcing him to drop what he likes
