I think it was terribly inappropriate. It is no one's business what step you are on except yours. You choose to experience the steps with your sponsor, you choose to let them know what step you are on. If you chose to speak at a meeting about it, then it is your choice. The sponsor shouldn't refer to your progress at all. No one should take your choice away. Personal information about your recovery is yours. What if your 4th step wasn't done, would the sponsor have said "Sally isn't doing so good on her 4th step." What is to stop them from saying that about your 5th? Boundaries stop it. Sorry this happened.
