When people say.....?

My boyfriend is just like you, it can be frustrating arguing with him for a few reasons. His thoughts are very well organized and quick to draw upon, so his stat quoted arguments are hard to combat. However, I still feel as though I am correct but I just have problems expressing it so quickly and my answers are not based on real references, simply experience, so its hard to make him realize what I am saying is valid. As a result he never changes his opinion and admits I'm right, that is very frustrating, there are anomalies and having a references doesn't prove everything. Even if I change my opinion to believe him I still sometimes feel shut down and stupid. All these things could be expressed with a frustrated "you just think you're so smart!" and If i were to say that to him, that is what my meaning behind it would be.
