I hear ya. The thing is, you are young yet so I don't think you have to worry about "wasting time". If you're happy when you're with her, it's not "wasted time", even if it doesn't work out in the long run. It's obvious you care about her from your posts and I'm ironically in a similar situation -- great girl, she's kind of "out there" and distant and I panic about how she feels quite often. What I'm doing is waiting for this girl of mine to come back to normal....that may be the wrong thing to do but she's important enough to me to give it a chance. And I'm a lot older than you so it might REALLY be a mistake for me...but I guess my personal advice is just give her some more time.
