I met her about 2 years ago, we didn't talk much. Then after a short period of time she decide to join the army, and she ask for my advice (I was in the army reserve), I told her everything I knew, and I didn't like her at the time. Then after a few months, there's a new semester, and we have a class together, since I was the only she ever talk to in the class, therefore we became friends. Then after while, I realize I have a crash on her, and she kept telling me about her problem with her boyfriend at the time(her ex-bf now), and we also chat about other things. We did spend a lot of time together, but I really don't think I am her type. However, after the semester she stop talking to me, and she only talk to me when there's no one else she knows around. After that semester, which is this semester, I only saw her twice, I did try to avoid her, but that's only because she made me felt I am on drugs, every time I see her I want to see her even more. And once I e-mail her an youtupe video, and ask her opinion about, she replay almost two weeks later, and she didn't tell me hoe she felt about the video. Next semester she is going to the army basic training, which I kept telling her not to go. And I want to tell her about how I felt, but I am not sure if I should tell her or not. What should I do?
