Welcome back to the Wefugees Community and thank you for sharing your situation with us.
If you are married to an EU citizen who is entitled to the "freedom of movement" within the EU (she is an employee in Germany, for instance) and you actually live together as a family, you have the right to stay in Germany as well. Please see section 2 of the Freedom of Movement Act/EU for more details. Your marriage is recognised/registered in Germany? If yes, I would not see a problem regarding the extension of the residencey permit card. For a full list of the requirements, you may also see this website (tailored for applicants living in Berlin though).
Do you agree dear @mbeon-fardeen or @mbeon-Christine?
In any case, please also don't hesitate to get back to us with any further questions.
All the best,
