well r/atheism I'm in need of some outside advice

I am a somewhat open atheist. My friends/ family all know and are okay with it being that most of my family is somewhat atheist. My girlfriend however is a hardcore Christian. This doesn't bother me in the least we just rarely speak of religion. I met this girl a few years ago and instantly wanted to call her mine, however, she was dating my best friend at the time. So I waited. Then when they broke up I spilled my guts and got hard core friend zoned. So I waited more. finally after about the 4th douche bag in a row she decided she would give the sweet nice guy a chance. We dated for a little less than a year and during the summer she decided to go to a christian camp. me being an atheist refused. She returned and promptly dumped me for Jesus. Time went by and we started dating again.I tried to change and give way to new thought by attending church a few times and even reading some of the Bible. Today she left for church camp again basically telling me I'm atheist, and I don't make her happy anymore. However, she is going to think and talk to Jesus at church camp this week on whether she should stay with me. R/atheism what should I do? I am a full on atheist and I highly doubt quoting more scriptures will change my mind. I this girl more than anything and have given everything to her.... should I just give up on a girl I've been chasing for the past 4 years? (sorry for the long post and poor grammar...)
