Welcome to the Wefugees Community and thank you for reaching out to us.
Am I right, assuming that your wife is German and you are holding a residence permit according to §28 of the German Residence Act? In that case (also when holding a residence permit acc. to §29 and "30), there is a possibilty to get an independent residence permit (according to §31 of the German residence Act) after the divorce. However, one requirement of that independent legal status will be that the "marital cohabitation has lawfully existed in the federal territory for at least three years".
To discuss your individual situation in more detail, I would highly recommend you to consult a lawyer or to visit a migration counselling office (which offer their services free of charge).
However, please also don't hesitate to get back to us with any further questions.
All the best,
