Dear @Sambright,
Welcome back and thank you for reaching out to us.
We discussed this issue a few times already at this platform - you may want to check this thread, for instance. My colleague explanied on this matter earlier:
"The basis of 25 Abs. 5 is, that a person with a Duldung cannot return to their home country. If a person has 25 Abs. 5 and then returns to their home country, then the very reason they were given it is removed and they could potentially lose their status."
I am afraid that we can not provide a final evaluation of your individual situation here and can only recommend to consult your lawyer on this. As you seem to have issues to trust his/her assessment, you may want to contact a refugee/migration counselling office for their support and professional opinion on your lawyer's work.
In any case, please also don't hesitate to get back to us with any other questions.
All the best,
Meike
