Will my relationship last after girlfriends celibacy?

Been with girlfriend for going on 4 years, majority of really happy times, the odd argument here and here of course. Having enjoyable sex often! My girlfriend has always wondered about Christianity, as both her parents are devout christians, I am however pretty damn athiest. I however, encouraged my girlfriend to persue her faith, instead of putting an athiest look on things. However now, after being a few times, she’s completly changed and given herself to god. Again, I am happy she is happy. But now wants to not have sex before marraige, (forgetting the hundreds of times we’ve actually done it) and tells me she’s ashamed to have slept with me. Long story short, I originally left her, saying that having no intimacy will kill our relationship, but after a couple of meetings of trying to call it off, we failed miserably. Although in break up mode, we still made each other smile, laugh and want to stay together. I’ve decided for the benefit of the relationship and time spent with her, to be with her while she ‘serves god.’ But I do however, now feel less of a man for doing so. I can’t imagine having my hands on another woman but this is driving me crazy. She used to love sex! Will my relationship last?
