Girls keep guys around who have intelligent minds and can hold good interesting conversation.
There aren't a lot of guys like this, which is why the girl wants you as a friend.
Her reply basically means that you are funny, interested and have your "conversation game" down to a tee. BUT... she's placed you in the "like-minded friend" box, because you fail to show any capability to dominate her sexually.
To put it another way, she's alright with you in her kitchen, but not in her bedroom.
Your next step should be to work on overlaying a sexual vibe onto all your conversations, this'll help you exponentially. Basically, lead her by touch, hold eye contact for abnormal amounts of time, fiddle with her hair occasionally (make sure she looks her prettiest.) Hope I helped
