She always acts so entitled and treats people she used to hate better than her best friends. I never yelled at her, but she's pushing my patience. She forces my boyfriend (he's also in our friend group) to read the Bible with her and tried to tell him the secrets I told her over the years, saying that if we're dating, the secrets must come out. I have nothing against her having a Bible group she just keeps trying to get me to join (I told her no over 10 times). She started ignoring our friend group, with whom she'd normally hang out around twice a week, and started a Bible group. I tried to make her happy and listen a bit, but she could tell I had no interest and yelled at me to turn to God. She started bringing a Bible to school, getting upset with anyone who cussed, and trying to convert people, even knowing they didn't share her beliefs.
But recently, she said she 'saw the light' and has been a hardcore Christian ever since. I'm an atheist and she used to have the same beliefs as me. She was openly lesbian with Christian conservative parents, knowing she liked girls her entire life, and I having only just come out as bisexual 2 weeks ago. My friend and I have known each other since 4th grade and have been practically inseparable that entire time. (English is not my first language, so bear with me.)
