For one, it's not a monologue, as we've been having an exchange of words. Personally, my life is rich in meaning because it is rooted in the One who imbues meaning and creates with purpose. And I think the fact that you so clearly believe there is meaning to be had even when your worldview denies the objective reality of such things is a sign of naturalism's weakness. Your decision to turn away from or towards theism is entirely your own.
