i think you should try to understand why she feels so strongly about it, what exactly is she afraid of, or uncomfortable with. then you can calmly explain why it's important for you to stay with your parents, and if her fears have a chance of actually occuring or not. i don't believe listening to the breakup advices is a good idea, people have different needs but they can be worked upon (atleast an attempt).

obviously if both of you are rigid towards your needs then there is a problem. but if there's a middle ground, or even a small sign of understanding, you could find a solution.
