Although Grizz offers supportive suggestions, the dynamics of why and how a father molests their own child(ren) is based upon control and this man isn't going to respond to threats, of any kind. Threats are useless against such predators.
The only way to make him stop is to tell someone. Whether it's your mother, or someone with the authority to make him stop, this is not your burden to bear - you are not responsible for this man's actions and choices, on any level. You don't deserve this abuse and betrayal, nor is it your fault that you've been harmed.
You are priceless and unique in this vast Universe, and you cannot be replaced. You are precious and important, and someone whom you had no choice to be a trusted guide and role model has betrayed that trust, and you are not at fault, under any circumstance.
I hope that you will post back and let others know what you did to save yourself, and how you progress through your recovery and healing processes.
My most heartfelt best and positive wishes to you, my dear.
