If you break off the engagement because she's jealous, you're shooting yourself in the foot if you then proceed to get together with the very person she was jealous of. It justifies her jealousy, and outs you as a cheating bastard.

"Red Fairy" sounds like a pleasant nickname, though.
If you answer a question with a little more than a simple sentence, you're not talking too much. You're just better at conversation than your average dating app girl.
Now, if Joseph changed that much, I'm inclined to blame the girl. Often is the case, but not always. He could just be a cheating bastard.

Kind of unusual for the MC to "just" be the daughter of a count, since it's a middle noble rank. It's almost always a duke, though once or twice I think I've seen a margrave.

Honestly I like it more when a villainess is OP for hilarious reasons, but I've noticed that the recent trend is "She's not even a villainess, she's just an anti-protagonist"
