I'm sorry for being so dense, but wouldn't it be more worrying if he said your therapeutic relationship wasn't fine? I'm not sure I understand, so I apologize. Is it because he described the relationship as therapeutic? Because I don't think he could call it anything else (if he did, then that would be a problem). Anyway, I think none of what he says sounds like he's leaving. It sounds a lot more like he's feeling good about things.
