What should I do if I want someone to get out of my world completely?

First of all, deal with it coldly, don’t contact him or her, and show the happy side of your life without him or her. (For example, post on Weibo)

Then, make an appointment and explain everything clearly, and be sure to emphasize that you don’t want to see him again.

Finally, cut off all contact methods (such as QQ, phone calls)

Then you can pursue your own happiness~

Hope to adopt it
