First, she wants to break with the past as soon as possible and get out of that sentimental life as soon as possible. She is denying the past and should review herself.
Second, after breaking up with her boyfriend, she was very complicated and upset. Constantly remembering, I haven't fully come out yet, and I'm still struggling.
It also shows that it is easy to break up, but it is difficult to forget a person and a relationship. So there are always people who make up after breaking up, that is, the separation and combination in marriage and love, which makes things more difficult.
If you are her boyfriend, you can comfort her. We can still be friends after breaking up. Why can't friends help each other?
