I think it can be easy to fall into the trap of "if T really knew everything about me, and truly understood everything, then she would feel just like I do"... I think someone else posted similar feelings about their csa (it was maybe several months ago... might have actually been you, but it's all vague in my head, so apologies).
Part of what makes csa (any abuse really) so damaging is that the guilt inherent in it brings up feelings of responsibility. Yeah, you might be able to look back with your current learning and understanding and KNOW that you could have said "no" or walked away, but what's the reality of that at the time the abuse was ocurring? many factors go into vulnerability to csa: the relationship to the person initiating it, previous learning around authority and choice, fear, confusion, and a lot more... even adult abuse survivors look back years later and berate themselves for not leaving sooner. they blame themselves for staying in a dangerous situation, but at the time it was the "safest" choice for whatever reason...
I second what guilloche said, perhaps try conceding that, while T may not be correct, she may also not be incorrect.
I can totally relate to how you are feeling though. I go through similar bouts often... It's always easier to see the good in others than myself though...
