It is important now that you address your feelings immediately. Don't wait! She may not even realize it, call it crazy but it's possible. Don't assume she has a crystal ball and knows exactly what you are thinking. She sounds busy with school, work and trying to manage a serious relationship with someone that has more free time at the moment would be hard to balance. Remember we can do anything temporarily, just make sure that you both want the same things and keep the lines of communication always open. She's your friend, remember that. She'll listen.
