You need to be careful with childhood memories, for many times we have unconsciosly altered them- sometimes actually creating 'memories' which never happened But if you are certain there was abuse, then do something about it If you need help dealing with it, that help is out there At worst, become active in not allowing it to continue- there are some things in this world we would be better off without and childhood sexual abusers are one of them My sisters were abused and had my Dad not died before I was old enough to do something about it, I would be serving a life sentence in jail for killing him so I guess I am lucky sometimes I am not recommending this method to deal with abusers but don't sit idly by when you know about it- at least call the authorities so someone will deal with it. All children deserve better than to be abused
