SAWE, lots of T's are fine with being a sounding board for a while, if you're getting something out of it, but some won't be comfortable billing your insurance if you are no longer struggling emotionally/behaviorally. And some will encourage you to stop "using" therapy -- for some people, going to therapy and not trying things on their own can keep them stuck. So I think there are different reasons why a T might want to try to "kick you out" if things are all better. But I don't think a T will try to make you leave before you are feeling ready to deal with it. If you aren't ready, I think that can be a problem to talk about in T, too.
