What is the ending of J and W?

J and W ended up with W texting J to say goodbye and never showing up again. W's short message content: human nature is very complicated, and love always makes people feel that they are suffering from loss. I hope we will not be separated by misunderstanding, negativity and contradiction. I have always believed that I can cure you and we can become better. After fantasizing about many of us, you used to be my world, but slowly I found that everything was just what I thought. I can't go on. Goodbye J, I believe you will be better off without me.
