Dig, first great job on 9 months and I think you made a wise choice regarding the girl you like...if it is meant to be it will be.
As far as your sponsor is concerned I would consider his comments to be a huge red flag.
My sponsor had similar views regarding people who were sober without aa and we parted ways early on in my sobriety. Just because someone is a "sponsor" does not make them wise nor knowledgeable. Ignore the ridiculous and continue on your path!
