Surprisingly she isnt, she will look heartbroken to leave Joshua but after saying goodbye to him she will leave. I guess she started to notice that shes not suitable to be by his side anymore since she cant look at situations clearly and treats everything and everyone around Joshua as threats, which will never be beneficial to him. She isolates him and thats extremely unhealthy
I bet she's just trying to get sympathy since she knows Joshua will be against her leaving the duchy. I bet she's shaming something fishy.
