The problems between siblings in our family were caused by parents.
I do not talk to any of my three brothers.
One was aware that I was being sexually abused by our father as a child, and never said or did anything to help end it. For the last 20 years he has denied ever telling me that he knew about it.
My youngest brother and I do not talk because 20 years ago I reported he and my second brother being sexually abused by our father to the authorities. They both said I was making it up and that nothing had happened to them.
Since then, they have both come out and said that they were abused after all.
Now my second brother will not talk to me because I tried to do the right thing all those years ago.
I do miss them, well, one of them. Mind you, it makes Xmas a darn sight cheaper, though!
