I don't think my sponsor would ever blow off commitments or decline a meeting if I asked her to go.
Life happens but I just can't imagine her saying "lets bake cookies instead"
I have had fun with other woman in AA were we did not discuss AA much, we just had a good time and that was fun but if I came in upset about a life issue I can almost guarantee it would change to a recovery conversation right quick.
I am not sure what is going on with your sponsor but it sounds like something is not right there.
I hope you find someone else, even a temporary sponsor, soon.
