It is clear blackmail from your superiors. Why comeback with same company? Also if you get married, better you & your hubby to be in the same place. Don't be afraid to loose your job here. As you said, your mom is in Germany, why not ask her to help you get a job in Germany? Or there are other reason of your emergency leave. Either way, decide wisely, since you'll get stuck with your present company for a long time if you don't make the move now.
