How do i keep a friend who is very religious?

Ive been friends with my friend krista for 9 years now. i moved away but we still talk. we drive to visit each other once a year but its not at all perfect. i cant be myself around her because during the period in which i moved away to now, ive discovered i was gay. i told my friend krista and her reaction was not as i expected. she threw the bible against me (verbally)... saying its a sin.. its not right...that its a choice.. that i should follow the bible... but what about happiness? what about being yourself? being true to who you are? we are still friends, barely. i love her to death... but i dont think she accepts me for me.. she ignores it.. and i cant talk about my life because im living one big sin.. 9 years and yet she would end it because i was gay.. i respect her religious views. im not saying her beliefs are wrong. but what about me? friendship? happiness?...could i make this friendship work or should i do what i fear and tell her we cant be friends.. because in the end, she doesnt accept me for me... its the sad reality...
