Get out before she gets pregnant, you obviously married way too early if you weren't even on the same page spiritually, and you can't force yourself into believing something you just don't believe. Enough with all the "sex isn't that important" crap, it is, a bad sex life is the primary cause of divorce so don't think you can ignore that. Eventually you will get sex somewhere, probably not her, so why stay married then?

Just remember the longer you stay with her, the more you pay in vaginamony, and if you have kids, you will be screwed up financially, (not to mention the kids themselves will be screwed).

You can try counseling but it really doesn't sound like she is right for you anyway, those deep emotional issues she has with sex vs religion won't go away quickly, if ever, so it might be best to just part ways while you are still young.
