I agree, if you're having doubts, either this guy is not the guy for you or you're not ready.

In reading this post, it's very clear that this guy is a good guy on paper. However, without chemistry, I fear you'll soon fall into the living like roommates thing. No, you don't need Prince Charming, but I honestly think your relationship is lacking. I guess I just don't understand why you'd settle (yes, SETTLE!) for a guy that doesn't make you feel passionate inside?
