My mum got divorced when my brother and I were 3 and 4 years old. Since then she has worked hard to give us a decent life. My brother has been having behavioural problems since then, although he is not a violent and antisocial person, he can't cope with social rules such as being punctual and follow family rules. He's 30 years old now and doesn't want to leave home to be independent. He likes skating and go out with friends. He works sometimes from home on the computer. He went to work to another city for 3 months but now he's back home. He feels attacked when my mum tells him that is for his own good to live on his own so he will grow up. He and my mum don't get along well, she complains, he reacts badly. I live in another country now with my husband but this family issue really worries me. What should my mum do? Thank you.
