How am I supposed to answer the question "Why do you love me"?

notice my guy asks WHY do you love me not what do you love ABOUT me?????????? I defiantly know what I love about him. His smile, how corny his jokes are and yet I laugh anyway, his intelligence, the fact that he stays up till one in the morning to talk to me, the way he shows me how to load a gun then laughs when I do it wrong, his kindness and how he cares for my safety. Every little thing that makes him who he is.
