Maybe being in that room as an adult will reinforce the knowledge that he cant hurt you anymore. I cant go anywhere near where I was abused. When I go see my Granny I have to drive through the town, and I will go an hour out of my way to go around it through the back roads in order to avoid it. I cant wait for the day when I can drive my car right in that town and stop at that sushi bar (the one thats his favorite place). And sit down with my friends with complete confidence and control. Knowing that if he walks in that he no longer has any control over me and that I am a better and stronger and happier person than that miserable piece of shit will ever be. What you are doing is admirable. I wish I could do that so much. I hope that being there is empowering for you. It brings me to tears.
