Yes, this type of situation has happened to me before. After a few frustrating sessions, we agreed to disagree. But I wanted her to apologize. Of course, she didn't feel a need to apologize for something she claims she never said. I gave her this analogy: imagine a mother watching their child ride a bicycle up and down the sidewalk. The child hits a rock, stumbles and falls and begins crying. Would the mother say, "I can't say I'm sorry since I wasn't the rock ... I wasn't the thing that directly caused you pain?" No, a mom would instantly hug their child while saying "I'm sorry you got hurt." My therapist thought for a second and revealed, "Yes, I understand. I'm sorry our misunderstanding is causing you so much pain. And I will try to remember these nuances more carefully in the future and I hope you bring up in the session if I said something that hurt your feelings." So we did move pass the incident. The relationship is more important in the long run.
