Thank you for explaining what you meant about financial abuse Araabra and it reminded me of a friend of a friend (UK) who has cut off his mother. When he was a child his father died in an industrial accident, a considerable amount of money was awarded to not only the deceased's surviving wife but also to his baby son for when he came of age. The trust was put in the care of his mother and by the time he had come of age she had almost blew the lot, not on the boy but on herself. I have also heard of similar stories in news items where parents have spent trust fund monies intended for their children, so yes, I understand what you mean and can see why a parent might be cut off for financial abuse in this respect.
I was smacked as a child and so was my husband, we were children growing up in the 50's, it really wasn't perceived as abuse back then, it was accepted that if you were naughty then you might get a smack on the bottom or legs. It really was just how it was back then, neither of us feel as if we were abused because we got a smack, neither of us cut off our parents because they smacked us as children and we did not stop them from seeing their grandchildren because we were smacked as children.
However, as I mentioned earlier I would not have accepted my children being smacked (spanked) by my parents or parents in laws.
