Cancelling permanent visa

I am going through the same problem now and am currently going through a separation. We have been living together for 3 years and I was given a permanent resident visa based on stable union. She is telling me she is going to the PF to get my visa cancelled so I have to leave Brazil because I gained the permanence because of her. I have made this my home now and am deeply rooted in. I have never broken any laws.
Any new clarification on the new laws and is this highly possible.

Already replied on the other topic.  Overall cancellation is not in her hands and is the decision of the Policia Federal

CEjames, your permanency was canceled??
