Sounds like a typical brotherly thing to do. I hope your "good" memories continue to carry you through. It sounds like he has some deeply rooted resentments and misunderstandings. You mentioned that he had spent a lot of time with your father before he died. Maybe he has never gotten over grieving for your Dad. Death and dying can be very confusing and upsetting for children. Unfortunately, they don't have the capabilities to ask for help or know what to do so they often suffer in silence. It does strange things to their minds. Good Luck. God bless.
