Hi @Joman,
If you were married at the time of receiving your permit, then it is possible to bring your wife here. However, as referenced by my colleague and as written in paragraph 29, this can only happen for humanitarian reasons. The authorities involved in the family reunification process (the German embassy in the country where your wife resides and your local Ausländerbehörde) have a certain amount of discretion on what they consider to be sufficient humanitarian grounds. You would have to show that it is not possible to live together in another country and that you will be living in Germany for the foreseeable future. You will also have to show that you earn enough to support your wife, have enough living space for her and that she has basic A1 level of German.
Here is some more information in English (via an online translation):

The link starts of referring to residency 25b Abs. 6 but then goes on to discuss family reunification for people with 25b Abs. 1.
Best,
