Apart from anger issues, her demand isn’t bad, as in unexpected, she’s probably new to your place/city so she doesn’t have any other place to temporarily shift to, she HAS TO adjust with your lifestyle, but seems like she can’t or doesn’t want to, it’s fair as she’s marrying you not your family or how your house “rolls”. To her, it seems you and your family are still strangers, she hasn’t “accepted” your family yet.
I’d suggest talk patiently, and hear her side well, and convey your problem and the steps taken by your parents well too, come to an understanding, try the least to say. Before jumping to either options given by her.
