My mum constantly shouts and belittles my elderly father who is 2 years older than her. They are both in their 80s, but when I question her about it she just starts shouting at me instead and blames my father for everything. I have often walked in on her shouting and abusing him on a regular basis, often about the same trivial matters, week after week. My father who is quiet, just sits and takes it, as I suppose he knows no different, but he is getting more old and frail by the day.
My other siblings don't live as near so don't know how bad it is, but I am constantly worried about their health and what it must be doing to them.
How do I stop my mother with this horrid, constant abuse?
