Hello DavidMishan, Thanks for using Microsoft products and posting in the community. You seem to want to quit your current Microsoft Home Group and join your partner's Home Group;
All you need to do is follow the steps below to opt out of your family group:
- Log in to family.microsoft.com using your Web browser.
- Click next to your name and select “ Leave Family Group ”.
- Select Delete to confirm.
I hope this helps, let me know if you have any questions and I will continue to support you.
Best Regards,Arthur - MSFT | Microsoft Community Support Specialist
