And I read the OPs post as a comment on she has given up trying to convince him.
I am just happy that when I decided to follow the PB, and I presented the idea and thinking to my partner, he was on board he said, if it would help me. Sometimes this guy drives me absolutely crazy, but other times he is just so great. The only thing he hasn't given up is those gluten free Mary's crackers. He must eat half a box with almond butter every day, but he's not fat anyway so who cares.
