Thank you for reaching out to the Wefugee Community!
I found this website on which you can find all sorts of courses and activities near Recklinghausen: https://www.kreis-re.de/Inhalte/Buergerservice/Leben_und_Wohnen/Kommunales_Integrationszentrum/Integrationsangebote.asp?db=594&form=list&top=499. Maybe you find something suitable for you here.
Depending on your individual situation you might also be able to get a financial support with a language course from the jobcenter or Agentur für Arbeit. I am sure that a migration counselling centre would also be happy to support in finding a solution for you.
I hope this helps.
All the best,
