Wow, didn't realize you were so young still. Not that it matters but it DOES put a slightly different perspective on things. You're young still man, you don't have to rush anything. I mean shit, you're probably still at home under the folks' roof right? Just keep the conversation light when and if you tell her how you feel. Just have fun and take it one day at a time. Anything can happen in the course of a year. Don't feel like you have to everything in ink because you're feel like there's a deadline before she moves. But it is nice to hear you had a great time with her and its fine that there was no sex. She'll end up respecting and trusting you more that it didn't go down like that right away.
