Well, I suppose it depends somewhat on their theoretical orientation but... generally, no, it's not a therapist's job to tell you what to do, and it's not likely to be therapeutically beneficial for you. "Casual conversation" doesn't sound right to me either to be honest.

I would like to suggest, though, that you bring these questions up with him - it's okay to question him about his methods, he's meant to be there for you after all!
