So recently, I began spending more time with a girl whose been a friend of mine for a while, and now its turning into something a little more. We've been on a couple dates and don't get me wrong, I think shes retty amazing. Shes attractive and very smart, and gets my sense of humor. I haven't been the eye of really any girls in the past, and typically am horrible with them, so its unique to find someone so special who likes me. The one problem is, the one thing I enjoy and have any knowledge about and talk about with other athletic people (running) she has no clue about. How do I work on talking about different things? I honestly have trouble talking about anything else. I shouldn't let this be a deal breaker right? I just don't think we have a lot in common and I don't know how exactly to approach this. Help?
