You have lost the therapeutic relationship, whether or not you keep in touch as friends. It sounds like you're trying to keep the therapeutic relationship by avoiding to address her as a friend. I may or may not be right and it's important for you to find your own answer here. Personally I think this is exactly the reason why friendships after therapy are not indicated (or at least there's a long waiting period before you can do that). I think keeping in touch as something other than therapist and client can deprive a former client of the natural grieving process. My therapist and I occasionally meet as colleagues at certain events (we don't go together but we're in the same professional community so it happens) and I've come to realize that should we end therapy, while we would still meet now and then, our relationship would NOT be the same, not as close, not as deep. It would still be a loss. I hope you will find some way of helping yourself through this situation and that you will do whatever is best for you.
