Is there really a girl for me?

Why is it that virtually every girl I like is a devout Christian? I'm agnostic and NOT Christian... therefore I don't pursue relationships with deeply religious girls as I know that religious differences would end the relationship quickly (if they didn't prevent it from starting in the first place). I've only met one girl that isn't Christian that I like, but she's already going out with somebody else. It just seems like every girl I like is either Christian or already going out with somebody... The only perfect girl (that was non-Christian and single) that I've "met" was in a movie (and she got together with a guy at the end). It just gets so annoying knowing that the only perfect girl doesn't even exist... I guess this isn't really a question-I just needed someplace to rant... sorry for the waste of an electronic tree...
