how great that you have turned to Wefugees with your question. If I understand you correctly, your spouse is now a German citizen and you have also been living in Germany for some time.
If you yourself have had a residence title here in Germany for three years (regardless of whether it was initially through your partner or whether you have your own) and the cohabitation with your partner continues, you may already be able to apply for a settlement permit for yourself. You will then automatically give up your refugee status with all its restrictions!
The permanent residence right of the settlement permit gives you the freedom to have your passport extended and/or to travel to your home country without giving up your nationality. To find out whether you meet the requirements for a settlement permit, it is best to check the website of your competent foreigners authority. In addition to the length of your stay, this includes questions about your livelihood, health insurance, criminal offences, German language skills (B1) and accommodation. Since your partner is already a naturalised citizen, I assume that you fulfil these criteria. You will also have already clarified your identity within the framework of the family reunion, so that the currently expired passport should not be an obstacle.
I wish you success and all the best.
