My mom still "uses" my younger sister who is mentally disabled to try to guilt me into having a relationship with them. It breaks my heart because my sister is caught in the middle of this manipulation and is unable to grasp the full context of what is going on. It was really hard in the beginning to stick to my no contact boundaries, but I know it's what I had to do. My parents are never going to change and it is not good for me to be around their toxic behavior. That really was the first step towards healing for me - accepting they would not change and if I wanted my life to follow a different course, I needed to put my needs ahead of their expectations. I still miss the concept of family, but like you, I don't miss them!
