looking honest and attractive but heart matter

I would like to meet someone who is just like me, yet opposite enough to be interesting...I'm a "nice girl" type, a "goody-two-shoes" who really likes either bad boys or nerds. I've dated both and currently am dating a guy who LOOKS like a bad boy, but is so sweet and loving on the inside (only with me)...but he is just not that smart...he bores me with the same stories over and over, and I worry that he'll bore me enough to leave him someday if I stay. I would love to stay with him if he had similar discussion and conversational abilities. Everything else about him is great...which is why I've stayed with him for two and a half years. Not sure I wanna give him up. He might just be the person I want to meet...but there's gotta be more! Piña Colada song-type situation, I hope
