Too often it is thought the ‘woman is always right, the man is always wrong’. That is a BIG BS. What is wrong with this mother? If what we have been told on this thread is correct, the mother is likely the one who is screwed up and possibly unfit.
Another point - mother is 56, she was 54 when this daughter was born. Quite possibly not a planned conception. This situation could very well make her a mental case.
Further down the thread you will see this was an adoption.
