i don't know if this is about a guy.
it sounds more like a friend tried to backstab her or something, and she realized she didn't deserve the way she was being treated by someone who was once her friend.
at first she cared about the whole fighting situation and thought she couldn't live without the friend, but she realized she didn't need the person in her life, and she was better off without them, hence her life being "clear".
she decided to put the past behind her, what happened happened and she is okay.
i can totally relate, the same kind of thing happened to me.
