I'm dealing with a similar problem. I'm the female version of yours. I actually think that everyone else summed this all up in a nut shell. I am the Christian in my relationship and I don't feel that you should force yourself to believe something you don't. I think you should figure out what you DO believe, why you believe it and discuss it with your lover. If she has a bad temper, be direct, but let her know you're not trying to hurt her. But you need to be honest; holding it in can cause deep trouble.
