This is a VERY helpful, timely article.
Before I went N/C with my family, my middle sister would periodically tell me that I was always the favored child in our family.
This could have an element of truth, probably because I learned early to stay out of the way and blend in.
That sister, on the other hand, never met a fight she didn't like. She was always getting in trouble with our parents because she just couldn't shut up. She is still like this today.
Going no contact recently was the best thing I could do.
