She tries to forget that someone but it won't work because of the memories that they have shared together. All she can do is to cry and feel the pain he did to her. Moving on is really hard, it takes time and a long process before you get over to it, and reality is really painful. The worst nightmare is when your someone says that he/she doesn't love you anymore, gets cold at you and no reasons of breaking up, especially for girls. It's totally a nightmare! If these really happens to you, then face and accept the reality.
