Sitting in the waiting area of the rehab building, my mother asks me what I think she should do, "stay here or go home". My instinct was to tell her that she had to stay but I told her that it was her decision to make, not mine and that I was not even going to give her my opinion as I did not want to be involved. She reacted with suprise and anger but I stuck to my guns and refused to give tell her how I felt.
She came out 5 minutes later saying she had decided to stay.
That was my boundary, I was not going to feel responsible for whatever she wanted to do so I needed to stay out of the decision-making process.
