I am glad that you are finding what works for you but it sure seems like you are not getting much protein every day. forgive me if I am wrong.
My husband was adamant about refusing to change his way of eating and over time he realized that the way he was feeling just wasn't worth it. He now eats like I do 98% of the time. I never tell him what he should or shouldn't eat because it will backfire on me if I do. Be patient, give it time, he'll come around eventually.
Of all the paths you take in life, make sure a few of them are dirt.
