Looking for advice.
My sister and I have noticed some narcissistic tendencies in our younger brother over recent years. His scapegoat appears to be our mother who he is abusive towards. She can not do anything right.
Our mother has admittedly distanced herself from him in the last 5 years, not intentionally I don't think, but through anxiety at being around him.
So a bit of background:
Dad longed for a son after two girls. He was into his rugby growing up and used to take me and my sister along. My brother was born 3 years after me and he put all his energy into him pretty much. Dad knew nothing about my sister and I growing up, didn't know who our friends were, couldn't tell tou what foods we liked or didn't. My brother on the other hand was his shadow and Dad pushed him into rugby- he was very pushy and sometimes nasty towards our brother when he didn't do things the way he thought. If he lost a game through partly his mistake, he would ignore him for days.
Dad was verbally abusive towards mum when he drank and she would stick up for our brother now and then but mostly stayed quiet. We have since learned that she was having an affair for many years whilst Dad's abuse was going on. My sister and I stayed out of Dad's way mostly as he would turn on us also if he was drinking, but we were much less of a focus for him than our brother.
Mum divorced Dad when my sister and I had left home and brother went to Uni, she had met someone else that she wanted to spend the rest of her life with. She remarried and moved 80 miles away.
My brother has inherited Dad's nasty side which is often unleashed when things don't go his way. Otherwise, he is usually calm, respectful and charismatic to be around. He hates our mother for divorcing Dad and spends much of his time at the rugby with Dad. Mum can not do anything right at all. He says that she puts more effort into myself and my sister- something I definitely agree with, but this divide emerged when we were youngsters and Dad didn't make much effort with us either- although my mum never missed any of
