America -> Germany for nursing training.

I have seen variations of this question asked on this sub but I am hopeful someone will be able to answer the issues specific to my situation. I am 24 and living the the US. My fiancé and I are getting married in 15 days. We need to leave this country due to reasons invoking keywords I don’t wanna post on social media anymore. My finances mother has dual citizenship to US and Germany. Our (loosely thought out plan) if for him to claim citizenship via his mother, then i will claim citizenship through him. I currently work as a certified ophthalmic assistant. My long term plan in the states has been nursing school. I have been getting my pre-requisites paid for by my employer. I understand that nursing in germany is different and is more of an apprenticeship, which is similar to how my current position was structured. I want to know what I, someone who is about to turn 25 and legally has no current ties to germany, can do proceed in finding training/employment for nursing. How much can i expect for a stipend, and how much can i expect for salary once trained. do my current college credits matter at all? I saw somewhere that 25 is the cut off for free training/stipends and need to know if i should expedite the moving process faster. we do not have any savings at this time. i am trying my best to learn german but B2 is a ways off at this point. any info/links would be appreciated more than i can express.
