This is sad. Like on that American Dad episode when Stan find's a "best friend" whom he agrees with everything on except religion, and Stan rejects him due to his own closed-mindedness. I apologize for comparing your situation to a simple comedy cartoon, but it reminded me of it. Anyways the problem is not you, it's her. She needs to (as stupidly idealistic as this sounds) accept you and your beliefs for what they are.
She wants you to "become a Christian", explain to her that if you did become a Christian, it would be a false belief, and you'd be lying to yourself and her. Tell her that you can't just "choose" to believe, because you believe what you believe already.
If she still wants you to become a Christian, then I don't know what to say man. Basically there are two things you can do: Try to reason with her (2nd paragraph), or undermine your beliefs.

School teaches you the lesson then gives you the test, life gives you the test, then teaches you the lesson.
