"You are so childish."
"I am going to stay with you through this."
"I won't put a time limit on how long you are in therapy."
"I promise I will be here."

"I know I promised you would be the one to decide when we end therapy, but I am terminating this relationship."
You've been terminated! Get the hell out!
When you leave, I'm going to have a party celebrating the acquisition of your absence.

You might want to think about trying hard not to be yourself. Maybe then you will be acceptable as a human being. Well, no, I take that back.

Now that I have therapized you to the point that you have dredged up wide gaping wounds, which are resulting in an increased neediness/clinginess -- I'm going to tell you how vile your clinginess is so you can feel hatred and shame, ok. that's done. NOW I terminate you. My job here is done.

If only you could have been someone else I wouldn't have terminated you. You are responsible for who you are and how you behave, including being disgustingly needy. This is all you, all your fault. It always has been and always will be.
