<human>: We're basically in a slump right now. And it just doesn't feel right anymore. We had a break up last month and now we're just compromising our differences and what made us break up last month, we're really doing great so far but recently she just opened up on how she really wants to serve her God and how much she loves him. 

She opened up about not having sex anymore and waiting until marriage. As a guy with the total opposite belief, I told her that sex is an important factor in a relationship(especially a long one) and I also told her that I've waited for her to be 18 before we've had sex with her consent too. And I just don't see why she should stop having sex with me even though we already had minimal amounts of sex. She even thought about breaking up again because I think that she doesn't like me anymore because of my belief. 

Sex  is just not the factor here. I never tried converting her into my belief and though she still tries to share biblical or christian things to me, I pretend to listen and consider what she says. I respect her faith and decided not to have sex for her happiness. But I'm afraid that one day (not too soon) she will really break up with me for being an Atheist.  It really sucks for me right now.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girlfriend for 5 years suddenly became full christian and doesn't want to have sex with me anymore until we get married. I'm also afraid in the long run she will break up with me for being an Atheist.
