When you say that it "didn't work", I have to ask, what do you mean, "it didn't work"? What was your expectation for sparking this argument? I ask that because often in the heat of the moment, we aren't really aware of what we wanted. Perhaps now, after the session, you know what kind of reaction you expected or wanted from him. I know that with my previous therapist (someone I grew to really like and appreciate) I wanted to get into a fight with her. I wanted a reason to walk away, to quit. I wanted to be able to say to myself, "She's an idiot and doesn't get me. I'm better off without her." I'm not saying this was your agenda, but it is helpful to really look at what you wanted or expected out of the altercation. And just so you know, a LOT of clients provoke an argument with their therapist. It is a situation rich with meaning. . . as long as you're willing to examine your own personal motivation and need for the altercation. Otherwise it just becomes another argument that goes nowhere, even if you believe you win the argument in your head.
