I went through something similar in my early years of sobriety but on a different note. I started to outgrow my sponsor. He ended up firing me because I couldn't make a lunch date due to an emergency at work. I apologized that I missed the lunch date and explained why I had to miss. He was very angry that I missed this lunch date and literally fired me for this reason.
I felt bad because he did help me out alot in the early years. But I started to put two and two together and realized that maybe he's not working the same program that he taught me. Years later I ran into him at a meeting and he said he had returned to drinking after 9 years sobriety. By this time I already had 9 years sobriety and realized that yes, I did outgrow my former sponsor.
