I have been estranged from a half brother for several decades. We had a brief reconciliation when my mother passed. I have no ill will tohis wife or family. He is critically ill. He has had paranoid tendencies and anger management problems that have caused has caused problems in his social relationships throughout his life, but failed to address these issues These problems also caused long term estrangementsbetween him and our mother prior to herdeath. It is sad for me because I feel I have been deprived of anormal sibling relationship. He lives a great distance from me and Iwill not attend the funeral, and am unsure of how to best handle mycondolences to his wife and children when the inevitable occurs. What would be the best way to approach this?
