Ok I am 17 in a relationship and saving myself till marriage. Now I am a southern/city girl (born in Alabama, raised in 'Bama, Georgia, and Brooklyn, New York), and Christian. My bf is atheist and his mom is a witch(like literal bruja wiccan). We are both virgins but me cause of my promise to wait till marriage and him cause he's with me and loves me. Any advice for keeping strong boundaries but still loving because we both just graduated (me a year early) and he's going to a SUNY school close to Canada and I'm going to Morgan State in Maryland?
