You are right about her business being none of yours. To the topic of her performance in recovery as your Sponsee, it sounds like the effort is missing. I do not live for my Pigeons, but I ask for simple considerations; do what you say to the best of your ability! You can't screw this up with her, just yourself, because you have to know she is in God's hands. All that is left is for you to give your part to God and move forward! Just a suggestion...
