You could ignore her because girls like attention all the time. I don't recommend it but you could insult her when you are together, by calling fat or something worst. On the other hand why don't you just sit her down in a quite place and tell her the truth. Just say you want to concentrate on your studies so you need some space. Telling the truth is the best way. Like the song goes ';Breaking up is hard to do';How can i get a girl to break up with me?
the best way is to man up and break up with her any other way is a cowardly move. cheat on her then your labeled a cheater, be mean and your a jerk. act like an honerable man and you will be able to hold your head high. if you try to get her to dump you you will hurt her even worse
