When I left my toxic family of origin, I attempted to maintain contact with some family friends and extended family members ... Unfortunately the manipulation of the primary abusers kept getting me slapped in the face by those I wanted to maintain relations with ... Therefore, I ended up having to sever all contact with any and all people in my past life that maintained relations with the ones I wanted to avoid ... I hope you have better luck with this, but I don't see how it's possible as the toxic person will always use others to try to get to you ... Sadly!
