How would you feel if your mother takes your child and then hands that child over to a known pedophile.?

I was ually abused by my stepfather and for three decades my mother has used emotional blackmail to slowing diminish my life with such devastation she eventually up graded to my children. Although i begged various welfare departments to investigate my mothers deliberate attempts to destroy my life, continued on the course of these so called child protection agency's, ignoring my rights as a mother, in trying to protect my children from the evil that is so ramp id here in Australia. They believed her lies, to which "mother" even knowing what this putrid thing had already done to myself and others, she allowed him access to my daughter. In addition to finding out all this, i decided to have him charged and for my effort, the DPP sat back for two years and watched my family sabotage all possibility in having him locked away for life, and manipulate the rest of my children away in the process. As a result i am unable to get any closer and still feel i am being punished for others criminal intent, and the government continues to turn a blind eye. I am a mother that loves her children, never abused them, and deserve an answer on why they "government departments and judicial system" allow this insidious evil to continually dissipate all our family's that endure it.
