I'm not sure that it would be helpful for me to elaborate on the countertransference angle. I don't think he consciously means to hurt you.

In any case, I hope you reflect on whether doubting how damaging your childhood has been to you has ever done you any good. I know you have a habit of telling yourself things affect you because you are weak in some way, but what if it's not that? What if you're the only one who can know the "truth?" I understand why you want your therapist's validation, I do. But please consider the fact that he doesn't know any better than you do in this matter. So don't let him mess with your mind.
