Did you point blank ask him if he wants to get rid of you because that is the message you are hearing. You might not like the answer or you might get your point across to him that his current intervention style is not working for you in the short term and if he strongly believes in it, then he needs to give you more explanation.

As far as why would he want to meet with you every week... from what I have heard and read, for therapist that go for this type of therapy, it is the puzzle that drives them, the puzzle to understand the world and experiences of another. So if that is the case.. why would you want "healthier" people... I quote healthier, because none of us is healthier than another... we all have our own brand of crazy (to quote someone here) and no one is better or worse, healthier or sicker, crazier or normal than another... in this way, we are all unique snowflakes of dysfunction.
