There is a reason for the second A in AA. She clearly stepped over the boundaries but that should not deter you from going to the group you have enjoyed and find comfort in.
Maybe one day in the future when you are ready to speak, you can casually bring up in group discussion how AA is a wonderful place to meet others and because what is said and who is present is private and not to be discussed by anyone outside of the meeting. Make sure you look straight at her when you say your nice eloquent comment.
Stay strong and keep going, because one day everyone around you will notice how awesome you are doing and you will not feel uncomfortable at telling anyone and everyone how great sobriety is.
