Dagny do you have to eat in the cafeteria? Are you in highschool? If so than that explains that you do have to eat there. I am just wondering if you have to eat at the same place he does because I am not familiar with your situation. Otherwise, it seems to me that you still have feelings for him. It is ok if you have feelings for him, they just do not go away overnight. If you can try to take yourself completely out of his life.
