How to keep a Cappy at arms lengths

You know I've asked myself that many times, what's wrong with him or me why I can't go further with him because we can talk and I enjoy spending time with him but I guess it comes down to it's just not there...I want the butterflies and this guy has never given me that or made me feel it could be there so I would be just settling and I don't want to settle, I want to be knocked off my feet I think I deserve that!
