I'm very sorry to hear that you're in such a situation.
I don't know about the permit regulations, but maybe the 'Frauenhaus' can help you. The hp is also in English.

According to the homepage they offer legal advise as well. So they should know how to proceed in your case. There are also a couple of threads concerning this theme when you use the search function. I didn't link them but I found a couple.
I wish you the best and hope you can move out soon!
