OKay I dont know if you believe this or not but she just does not love you. If she tells you that she still loves you then she is saying this because she does not want you to think that she does not. Maybe she thought that she liked you and all that before and kept fasts and all for you. Later she decided to take the easy way out and cheat on you and hurt you. If you are waiting for her to come back then I think it would be your stupidity. Lets say you guys even get back together... will you ever forget how she cheated on you and will you ever trust her? She hurt you and your ego so you want her back at any cost. It would be immensely hard to let go of her BUT the best thing to do is try to forget her. What I think you should do is involve yourself in your studies and other stuff so that you dont have any time to think about her. Time is the greatest healer. Stop contacts with her and if you cant do that then at least try to contact her in a minimal. You deserve something better. She was either blinded by something or simply did not care about you. Do stuff to divert your mind and you should be good... All the best!
