If you don't move on, you won't be able to get on with your relationships and life... This girl has a boyfriend she should break up before you even make a move on her. I understand at a young age, people think there is only one for them. Truth is you date several people to find what you like and don't like but you are carrying a baggage. You are wasting your time, she would not even break up with her bf for you. Move on, it sounds like she just wants your attention
