Hi @Musawvir,
I previously answered a question of yours about your situation here.
The information you received at the appointment is incorrect. The law around EU and non-EU partnerships in Germany is complex and so it is important you do not accept information about this as valid without checking it or having someone with experience in this area check it.
In my previous answer I detailed that, based on the information you provided here, you are entitled to a residence permit according to paragraph 3, section 4, part 1 of the law on EU freedom of movement.
I recommend you make a written application on the grounds of that part of the law and point out that you fulfil the following requirements:
- You are working
- You have been married over 3 years
- You lived together married with your wife for a least one year in Germany before she left
I cannot see any grounds on which they could refuse you a residency permit once you fulfil those requirements.
Best,
Éanna
