Welcome back to the Wefugees Community and thank you for reaching out to us again.
If I remember correctly from your last question, you also have a child with your partner, right?
We discussed a very similar question here before - you may follow the link to check it out.
At first, you will need to submit a so-called "Umverteilungsantrag" (application for relocation) at the Disctrict Government Arnsberg.
I read on their website that for a relocation process within North Rine Westfalia they are the agency to address. You find the correct form in the download section of the respective website.
A refugee counselling service may support you to fill the form if needed. The Caritas as well as the Diakonie have offices in Paderborn, for instance.
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
