No, I don't. If I recall correctly, you had worked out with him to be clean for a certain number of days (this was a while back, so maybe that's changed?)--that his concern is whether or not therapy is helping you when you're using, not that he wants to dump you or will dump you. It seemed like you might have been the one to initiate that because he wasn't sure what to do, that he just wants to be helpful and not make things worse.

Sorry if I got that wrong. Anyway, I don't think he will dump you. It's more about whether you will dump you.
