Again, I don't think you're petty at all. When we change and transform something does happen with our friendships. I remember when I chose to eat plant-based and vegan. I actually lost friends. I live in the south and everrrrrything is celebrated with food. If we went to the restaurant and I'd ask questions, I could hear the deep breaths and feel the suppressed eyerolls. My friends from college understood but those I knew before college started to avoid me. I realized I'd outgrown them in many ways. Love them, but we're different.
