what therapy is this?

Forget the shrink. We don't need her. Let's just pretend that you are in front of me, sitting in this chair. So I look at you, and it's show time!
Remember the times I told you I loved you? Well, I lied. Yeah, that's it. I just wanted you to believe that I felt something for you even when I didn't. I cheated on you only to feel good about myself.
You've heard me. I have never loved you! Why would I? Only because you promised me faithful love? Don't think so. You never listened to me. You were never there for me, and I won't forgive you that. I can't let this happen again, so I want to erase you from my mind. And that's why I confess: I hate you!
Wow, this feels good. I haven't felt like this in a long time. Since I've met you, to be more exact. So now you know it. I faked all the time. What are you going to do?: cry, hit me, leave? Do whatever the hell you want, you are nothing to me anymore. You don't belong me and I sure ain't part of you either.
What? Is this too cruel for you? But honey, you set the rules yourself. You gave me hope when you knew damn well how things were going to turn up. Well, with your permission, and if you would excuse me, I'm gonna twist this ending in my benefit. I want to be selfish and I want you to suffer the same things you've put me through.
As you see life isn't fair. Right now I want to hate you so much that I don't ever commit this same stupid mistake. I don't love you anymore. I never have. I've tricked and manipulated you as I wanted.
There, happy now?
