I was abused from the age of 6 untill the age of 12 when for some reason my abuser (brother in law) just stopped, I forgot all about it and actualy became friends with him untill I was 18 when I saw him playing with my neice and younger sister in a way that was not 'right' and had so many memories fill my head I could not believe I had forgotten them ! Of course I spoke up and he was arrested which is another story, but yes you can forget your abuse.
