Dear @AbdurRehman,
Welcome to the Wefugees Community and thank you for your question.
In general, if you are married to a German woman you are entitled to get a residence permit according to §28 of the German Residence Act. You will need to apply for it at the local Ausländerbehörde. However, please keep in mind that your residence will also be dependent on the marriage for three years. If you are still in the asylum procedure, you may want to wait for the outcome as well. If the BAMF will decide to grant you a refugee status or subsidiary protection, you will receive a humanitarian residence permit which will be independent of your marriage.
Please get back to us if I misunderstood your situation or if you want to discuss your case further.
All the best,
Meike
