>>1 a relationship requires effort from both parties to work, if she doesn't want to put in the effort then there really isn't anything you can do. You could tell her off but that just might hurt you more, in some cases getting that off your chest may help you but I don't think so in this case, your obviously mature about it all and probably don't need anymore of her to deal with. Friends drift apart, it happens, the two of you change and become two different people than you were before. You need to move on with your life and from her as well, make new friends and do the things you love and focus on school. It may be painful and raw right now but with time it'll get better, I hope that I've helped ^^
