Do you ever feel distant from your best friend?

My best friend and i have been best friends for 9 years, ive noticed that she changed and im growing further and further away. When i tell her what bothers me she sees it as betrayal to our friendship, even tho i was just trying to improve our friendship. I asked her for help about church and she doesnt seem to wabt to help me. Im new to the whole church thing i asked her if she goes with our other friend alex, she said yeah. I wanted her to ask if i wanted to go, but judging for our convo she didnt want me part of her church routine so i just said ok after she said yeah. I really dont know wht to do right now, i feel like shes pushong me away and i feel replaced bc of alex. She also went and told alex everything i told her to keep a secret when we had our last fight, when im out by myself with people outside of her "group" im more outgoing and i party more bc shes sooo quiet. I just need some advice an somebody to tell me what to do :/ its just so fustrating she doesnt understand any of this thank you
