Hello Thinkingloud: This problem strikes me as being one of boundaries. Are you familiar with California therapist Kati Morton? Kati is on YouTube, Facebook, Twitter, & probably every other social media site around, plus she has her own website. Kati uploaded a video onto her YouTube channel a while back where she talked about establishing & reinforcing boundaries. I think if you were to go to her YouTube channel, look back through her videos, find the one on boundaries, & watch it this might be helpful.
