I've just finished my first year at uni, and during the last term I really feel like I hit it off with a girl in my halls. However, we have two different sets of friends, so I didn't really get much of a chance to spend time with her, but we had the occasional chat during lunch and dinners, and everytime she walked past my room she'd look in and smile or say hello.

Thing is, I think I have a massive crush on her, but I'm not sure whether she feels the same, or was just being really friendly. We're moving into different houses next year, so probs won't see each other too much around campus.

Is it worth me sending her an email telling her how I feel, or just leave it alone?

Thanks
