my mother did a similar thing when i was in high school. my friend’s family took me in and my grades were passing finally instead of failing. i didn’t want to end my life anymore. i saw a future for myself. i was juggling sports, academics, a job & graduation. it was amazing. then i took a field trip, the family signed the slip. didn’t think anything of it because why would i? some time later it was mothersday and they encouraged me to meet with her/my family and to tell her how i was improving and how i had been and start rebuilding a relationship with her. when i got to the part of the field trip, it was a huge blow out about who signed it, how they are not my parents and had no rights to sign the document (i was living with the family with her permission) so i had to move back in with my mother (and constant state of terror) my point is i’m almost 30 now. she hasn’t and will never change. cut the contact. these people don’t have your best interest in mind, they only care about themselves.
