There are people who can walk away from you.
When people can walk away from you: let them walk. I don't want you to try to talk another person into staying with you, loving you, calling you, caring about you, coming to see you, staying attached to you.
When people can walk away from you, let them walk. Your destiny is never tied to anybody that left. People leave you because they are not joined to you. And if they are not joined to you, you can't make them stay. And it doesn't mean that they are a bad person it just means that their part in the story is over. And you've got to know when people's part in your story is over so that you don't keep trying to raise the dead.
