Hi Freefallin...I hope I can help.
Understand, hard as it is, he is never going to apologize, I don't think. He is never going to change from what he is. People like that operate solely because they can justify their actions, and that they are incessantly "right" and others are always wrong. He will always justify and distort the truth of the matter so that he can constantly justify what he's done.
You have every right to feel resentful! You are a better person than I am for still having ANY relationship with him whatsoever. That being said, I think it is of importance that you get out as soon as you have the ability to do so. Additionally, did your therapist understand your story? It seems...incredulous...to me that she'd have the gall to ask you why didn't you leave if you were merely a child....where were you to go? :/ If she still pins it as "your fault," which I can assure you it's not, I'd consider a switch.
By the way, I certainly understand I'm not a lawyer (yet

), and that I only have one year of my undergrad studies for my law degree done, but I don't believe in any state it's legal for him to do what he did to you. That is a load of BS, frankly.

Please don't lose faith in the justice system. You were wronged, I think, by that officer, but that is not representative of the whole. I just felt like adding that.
Please take care. I wish you my best, and I hope I was of some help.
