I can understand some of your fears around telling. I have never told my t who my abuser is because I know she is obliged to report him and that she would like nothing better than to report him.
Yes and if your dad is a psychopath, I don't doubt this for a second he will use all of him charm to manipulate anyone you report him too. It probably feels like you are stuck in a hopeless place, would you agree? You said your life wouldn't be worth living if no one believed you if you reported him, but is it worth living now if he can snatch you off the street?
Is there a way you can fight him yourself without reporting just yet. I wonder if you want to report this? Are you ready for this right now? I ask because in my experience reporting can do a lot more harm than good and often leaves the victim feeling more hopeless and abused.
It's hard to have any spirit left after being abused but could you muster up a little to see how you want to fight this, what feels right for you now?
