I am really sorry to hear about your stress and worries. However, I am afraid that we can not provide more information on your situation "from distance" - on a public platform. My colleague was answering you as good as possible already here as well as here. I can only support his recommendations to get individual help in a counselling office using the search engine he was mentioning in his last answer or this one, for instance. Any predictions about "what your chances are" would not be serious. I can only quote my colleague again who stated:
"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."
If the immigration office is not respond to your objection, it can really help to get support by an experienced social worker from a migration counselling office (which services are free of charge) or by a lawyer. Since you hired a lawyer already and apparently don't trust his actions/words, it can make sense to discuss your doubts in one of those counselling offices.
Please don't hesitate to give as an update on your situation as soon as you have some new information.
All the best,
